"problemDescription": "Problem: Generating a Weekly Meal Plan\n\nYou have been tasked with creating a program that generates a weekly meal plan for a family based on their dietary preferences. The program should take into account the family members' food restrictions and preferences, and suggest different meals for each day of the week.\n\nThe program should use the Racket programming language and be implemented in a single file.\n\nSteps to solve the problem:\n\n1. Define the dietary preferences: Start by defining the dietary preferences of the family members. This may include restrictions like vegetarian, vegan, gluten-free, or preferences like a preference for certain cuisines.\n\n2. Initialize the available recipes: Create a list of available recipes that are suitable for the family's dietary preferences. Each recipe should include information like the name, ingredients, and cooking instructions. Consider representing the recipes as a list of records, where each record holds the necessary information.\n\n3. Create a function for selecting a random recipe: Implement a function that takes the list of available recipes and the family's dietary preferences as input and selects a random recipe that satisfies the preferences. The function should use the `random` function from the Racket standard library to generate a random index within the range of the available recipes.\n\n4. Generate a weekly meal plan: Write a function that generates a meal plan for the entire week. The function should take into account the family's dietary preferences and generate a different recipe for each day of the week. To do this, you can use a loop or recursion to iterate over the days of the week and select a random recipe for each day using the function defined in step 3.\n\n5. Print the meal plan: Implement a function that takes the generated meal plan and prints it in a readable format. The function should display the recipe for each day of the week along with any additional information like the ingredients or cooking instructions.\n\n6. Test the program: Finally, test the program with different dietary preferences and verify that it generates a diverse and suitable meal plan for the family. Make sure to test different combinations of restrictions and preferences to ensure the program handles them correctly.\n\nBy following these steps, you can develop a Racket program that generates a weekly meal plan taking into account the family's dietary preferences and restrictions, providing them with diverse and suitable meal options for the entire week.",

The objective is to assign each person in the group a random gift recipient while keeping the assignments a secret from everyone involved, ensuring that the person giving the gift doesn't know who their recipient is until the gift is opened.\n\nSteps to solve the problem:\n\n1. Define a data structure to represent a person participating in the Secret Santa exchange. This structure should include information such as their name, contact details, and their assigned gift recipient. For simplicity, you can represent a person as a Racket struct.\n\n2. Create a function that takes a list of people as input and assigns each person a random gift recipient from the same list. To achieve this, you can use the `shuffle` function from the `random` module to randomly order the list of people. Then, assign each person a gift recipient by pairing each person with the person in the next position of the shuffled list, except for the last person who is paired with the first person.\n\n3. Implement a function called `sendNotification` that sends an email or message to each person participating in the Secret Santa exchange, notifying them of their assigned gift recipient. This function should take a person's details (name and contact information) and their assigned recipient as input and send the message accordingly. You can use the `sendmail` function or a similar method from a Racket package to achieve this.\n\n4. Finally, create a main function that ties everything together. This function should read the list of people participating in the Secret Santa exchange from a file or via user input, call the function that assigns the gift recipients, and then call the `sendNotification` function for each person to send them their recipient's details.\n\nBy following these steps, you will be able to create a single file program in Racket that takes a list of participants, assigns them random gift recipients, and notifies each participant of their assigned recipient, facilitating a fun and secret gift exchange among friends.",

The store has a wide range of products, each with its own unique code, name, description, and current quantity in stock.\n\nYour program should have the following functionalities:\n\n1. Display Inventory: The program should display the complete inventory to the store manager. This includes the product code, name, description, and quantity in stock for each item.\n\n2. Add New Product: The program should allow the store manager to add a new product to the inventory. The manager will provide the product code, name, description, and initial quantity in stock.\n\n3. Update Stock: The program should allow the store manager to update the stock quantity of a specific product. The manager will provide the product code and the new stock quantity for the item.\n\n4. Remove Product: The program should allow the store manager to remove a product from the inventory. The manager will provide the product code of the item to be removed.\n\n5. Search Product: The program should allow the store manager to search for a product in the inventory based on the name or description. The program will then display the product code, name, description, and quantity in stock for all matching items.\n\nSolving Steps:\n\n1. Start by creating an empty inventory dictionary, where the keys will be the product codes, and the values will be lists containing the name, description, and quantity in stock of each product.\n\n2. Implement a function called \"display_inventory\" that takes the inventory dictionary and prints the product code, name, description, and quantity in stock for each product.\n\n3. Implement a function called \"add_product\" that takes the inventory dictionary, as well as the product code, name, description, and initial stock quantity. This function should add the new product to the inventory dictionary.\n\n4. Implement a function called \"update_stock\" that takes the inventory dictionary, as well as the product code and the new stock quantity. This function should update the stock quantity of the specified product in the inventory dictionary.\n\n5. Implement a function called \"remove_product\" that takes the inventory dictionary, as well as the product code of the item to be removed. This function should remove the specified product from the inventory dictionary.\n\n6. Implement a function called \"search_product\" that takes the inventory dictionary, as well as a search term (name or description). This function should iterate over the inventory dictionary and display the product code, name, description, and quantity in stock for all products whose name or description contains the search term.\n\n7. Create a main program flow that presents a menu to the store manager with the available options (display inventory, add new product, update stock, remove product, and search product). Based on the manager's input, call the appropriate function to perform the desired operation.\n\nBy following these steps, you will be able to develop a Python program that effectively manages the inventory of a grocery store.","snippetDescription":"One particular function call in this program is the `display_inventory(inventory)` function call in the main program flow.\n\nThis function call is made when the user enters the choice \"1\" to display the inventory. It calls the `display_inventory` function and passes the `inventory` dictionary as an argument.\n\nThe `display_inventory` function then iterates over the `inventory` dictionary using the `.items()` method. It unpacks each key-value pair into the variables `code`, `(name, description, quantity)`. It then prints the code, name, description, and quantity of each product in the inventory.\n\nOverall, this function call is responsible for displaying the current inventory to the user."})

However, in practice, there can be various situations where the file may be empty, contain invalid timestamps, or have missing or incorrect data. To handle such scenarios, a programmer can add error handling and validation techniques.\n\nSome possible changes could include:\n1. Adding a try-except block in the \"calculate_average_speed\" function to catch any exceptions raised when reading or parsing the file. This can help handle scenarios such as file not found, read errors, or incorrect timestamp formats.\n\n2. Validating each timestamp before converting it to seconds. This can be done by using regular expressions to check if the timestamp matches the expected format (HH:MM:SS) and if the hour, minute, and second components are valid (e.g., hour between 0 and 23, minute and second between 0 and 59). Invalid timestamps can be skipped or logged for further analysis.\n\n3. Handling edge cases such as empty files or a single timestamp in the file separately. For example, the code can check if the file is empty and display an appropriate message to the user. Similarly, if there is only one timestamp in the file, the code can handle this scenario differently as there is no time difference to calculate.\n\nBy incorporating error handling and validation techniques, the code becomes more robust and can handle unexpected situations gracefully, providing a better user experience and preventing potential crashes or incorrect results.","updatedCodeWithSnippetDelimited":"```python\nimport datetime\nimport re\n\ndef convert_to_seconds(timestamp):\n time_format = \"%H:%M:%S\"\n time = datetime.datetime.strptime(timestamp, time_format).time()\n seconds = (time.hour * 3600) + (time.minute * 60) + time.second\n return seconds\n\n\ndef is_valid_timestamp(timestamp):\n time_pattern = r'^([01]?[0-9]|2[0-3]):([0-5]?[0-9]):([0-5]?[0-9])$'\n return re.match(time_pattern, timestamp) is not None\n\n\ndef calculate_average_speed(filename):\n converted_timestamps = []\n try:\n with open(filename, 'r') as file:\n for line in file:\n timestamp = line.strip()\n if is_valid_timestamp(timestamp):\n seconds = ★convert_to_seconds(timestamp)★\n converted_timestamps.append(seconds)\n else:\n print(f\"Invalid timestamp: {timestamp}\")\n \n if len(converted_timestamps) < 2:\n return \"Not enough data for calculating speed.\"\n\n time_differences = [converted_timestamps[i] - converted_timestamps[i-1] for i in range(1, len(converted_timestamps))]\n\n total_time = sum(time_differences)\n total_distance = 100 # Assuming the distance covered between two timestamps is 100 (example value)\n \n if total_time == 0:\n return \"Total time cannot be zero.\"\n \n average_speed = total_distance / total_time # Assuming average speed is calculated as distance / time\n return average_speed\n \n except FileNotFoundError:\n return \"File not found.\"\n except Exception as e:\n return f\"An error occurred: {e}\"\n\n\nfilename = \"car_timestamps.txt\"\naverage_speed = calculate_average_speed(filename)\nprint(\"Average Speed of Cars:\", average_speed)\n```","problemDescription":"Problem: Calculating the Average Speed of Cars on a Highway\n\nFraming:\nYou are working for a transportation agency responsible for monitoring the average speed of cars on a particular stretch of highway. Your task is to write a Python program that takes a file containing the timestamps of when each car passed a specific point on the highway, and computes the average speed of all the cars.\n\nThe file provided will contain the timestamps in the format \"HH:MM:SS\". Each timestamp represents a car passing the designated point on the highway. Your program should convert these timestamps into seconds, calculate the time difference between each consecutive timestamp, and then compute the average speed based on the distance covered between two timestamps.\n\nSteps to solve this problem:\n\n1. Define a function, let's say \"convert_to_seconds\", that takes a timestamp string as input and converts it into seconds. This function will use Python's built-in datetime module to handle the conversion.\n\n2. Within the \"convert_to_seconds\" function, split the timestamp string using the \":\" delimiter to extract the hour, minute, and second components. Convert each component from string to integer and multiply the hour by 3600 (seconds in an hour), the minute by 60 (seconds in a minute), and add all the components together to compute the total seconds.\n\n3. Define another function, for example, \"calculate_average_speed\", that takes the filename containing the timestamps as a parameter. This function will open and read the file.\n\n4. Within the \"calculate_average_speed\" function, create an empty list to store the converted timestamps in seconds.\n\n5. Use Python's built-in open function to open the file in read mode and loop through each line. For each line, call the \"convert_to_seconds\" function to convert the timestamp into seconds and append it to the list.\n\n6. Calculate the time difference between each sequential element in the list by subtracting the previous value from the current value. Store these differences in a new list.\n\n7. Since the distance covered between two timestamps is constant, calculate the average speed by dividing the total distance by the total time.\n\n8. Display the calculated average speed to the user.\n\nBy following these steps, you will be able to create a Python program that reads a file containing car timestamps, converts them to seconds, calculates the time differences, and finally computes the average speed of the cars on the highway.","snippetDescription":"A particular function call in this program is `convert_to_seconds(timestamp)` in the `calculate_average_speed(filename)` function.

If the quantity input is not a valid integer, an error message is displayed to the user. However, error handling for unrecognized actions and adjusting quantities is not yet implemented.","updatedCodeWithSnippetDelimited":"```javascript\n// Initialize an empty inventory object\nconst inventory = {};\n\n// Implement a loop to allow the store manager to perform different actions\nlet action = '';\n★while (action !== 'exit') {\n // Prompt the store manager for an action\n action = prompt('Please enter an action (add/adjust/view/exit):');\n\n switch (action) {\n case 'add':\n // Prompt for item name and quantity\n const addItemName = prompt('Enter the item name:');\n const addItemQuantityInput = prompt('Enter the item quantity:');\n \n // Check if the input is a valid integer\n if (!Number.isInteger(parseInt(addItemQuantityInput))) {\n alert('Invalid quantity.

The program should allow the store manager to add new items to the inventory, adjust the quantity of existing items, and view the current inventory.\n\nTo solve this problem, follow these steps:\n\n1. Initialize an empty inventory object: Start by creating an empty object to hold the inventory.\n\n2. Implement a loop to allow the store manager to perform different actions: Use a while loop to repeatedly prompt the store manager for an action, such as adding items, adjusting quantities, or viewing the inventory.\n\n3. Implement a switch statement to handle different actions: Inside the loop, use a switch statement to perform different tasks based on the input provided by the store manager. For example, if the store manager chooses to add an item, prompt them for the item name and quantity, and add it to the inventory object.\n\n4. Implement a function to add items to the inventory: Write a function that takes the item name and quantity as arguments and adds them to the inventory object.\n\n5. Implement a function to adjust quantities: Write a function that takes the item name and quantity as arguments and adjusts the quantity of the specified item in the inventory object.\n\n6.

Based on the entered action, the program executes a specific block of code. \n\n- If the action is 'add', the program prompts the manager to enter an item name and quantity. It then calls the `addItem()` function to add the item to the inventory.\n- If the action is 'adjust', the program prompts the manager to enter an item name and quantity. It then calls the `adjustQuantity()` function to adjust the quantity of the item in the inventory.\n- If the action is 'view', the program calls the `viewInventory()` function to display the current inventory.\n- If the action is 'exit', the loop is exited and the program terminates.\n- If the entered action does not match any of the above cases, an alert is displayed indicating that the action is invalid.\n\nThis loop body allows the store manager to repeatedly perform different actions until they choose to exit the program."})

"problemDescription": "Problem:\n\nYou work for a renowned furniture company called \"Elegant Living\" which specializes in custom-made furniture. One of the challenges faced by the company is documenting and managing the vast inventory of furniture pieces they produce. To tackle this, your task is to create a web application that displays a list of furniture items along with their details on a single webpage.\n\nThe task is to create an intermediate-level JSX program that fetches a list of furniture items from a local JSON file and dynamically displays them on the webpage. Each furniture item should include details such as the furniture name, price, material, and a brief description.\n\nConstraints:\n- You should use a constant to store the path to the local JSON file containing furniture data.\n- The furniture data should be fetched asynchronously using the fetch API, and the program should handle any errors that occur during the fetch process.\n- The program should iterate through the fetched furniture data array and generate JSX elements dynamically to display the furniture details.\n- Each furniture item should be rendered as a component and properly styled using CSS classes.\n\nSteps to Solve:\n\n1. Create a new JSX file and import the necessary dependencies, such as React and the CSS file for styling.\n2. Define a constant `FURNITURE_DATA_FILE` and set its value as the path to the local JSON file containing furniture data.\n3. Start by defining a functional component to represent the furniture webpage. For now, this component can simply include a basic layout with a `<div>` container.\n4. Inside the functional component, use the `useEffect` hook to fetch furniture data from the JSON file using the fetch API. Make sure to handle any potential error that might occur during the fetch process.\n5. Once the data is successfully fetched, parse the JSON response using the `json()` method and store the result in a state variable.\n6. Iterate through the furniture data array and create a new component for each furniture item, passing the necessary props such as name, price, material, and description.\n7. Style the furniture item components using CSS classes and ensure they are properly aligned and visually appealing.\n8. Finally, render the furniture item components within the main functional component and verify that the webpage displays the furniture items along with their details.\n\nRemember to break down the problem into smaller steps and solve them one by one while testing your program's functionality at each stage.",

The total cost includes the sum of the item prices, the tax amount, and the shipping cost. You need to write a Python function that takes the item prices, tax rate, and shipping cost as input and returns the total cost.\n\nSteps to solve the problem:\n\n1. Define a function called \"calculate_total_cost\" that takes three parameters: item_prices (a list of numbers), tax_rate (a non-negative number), and shipping_cost (a non-negative number).\n2. Inside the function, calculate the total cost by summing the item prices, adding the tax amount (calculated as a percentage of the sum of item prices), and adding the shipping cost.\n3. Return the total cost from the function.\n4. Outside the function, call the \"calculate_total_cost\" function with sample values for the item prices, tax rate, and shipping cost to test if it correctly calculates the total cost.\n5.
