I need help with one task

We are given a CSV file containing the prices of every item on every menu of every restaurant in the town of Jurgensville. In addition, the restaurants of Jurgensville also offer Value Meals, which are groups of several items, at a discounted price. Below is the file's format for lines that define a price for a single item: restaurant ID, price, item label for lines that define the price for a Value Meal (there can be any number of items in a value meal) restaurant ID, price, item 1 label, item 2 label, ... All restaurant IDs are integers, all item labels are lower case letters and underscores, and the price is a decimal number. We need a program that accepts... the town's price file a list of item labels that someone wants to eat for dinner and outputs the restaurant they should go to the total price it will cost them It is okay to purchase extra items if the total cost is minimized. Here are some sample data sets, program inputs, and the expected result: Data File [login to view URL] 1, 4.00, burger 1, 8.00, tofu_log 2, 5.00, burger 2, 6.50, tofu_log Program Input > program [login to view URL] burger tofu_log Expected Output => 2, 11.5 Data File [login to view URL] 3, 4.00, chef_salad 3, 8.00, steak_salad_sandwich 4, 5.00, steak_salad_sandwich 4, 2.50, wine_spritzer Program Input > program [login to view URL] chef_salad, wine_spritzer Expected Output => null (or false or something to indicate that no matching restaurant could be found) Data File [login to view URL] 5, 4.00, extreme_fajita 5, 8.00, fancy_european_water 6, 5.00, fancy_european_water 6, 6.00, extreme_fajita, jalapeno_poppers, extra_salsa Program Input > program [login to view URL] fancy_european_water extreme_fajita Expected Output => 6, 11.0
