This function takes what kind of animal or animals you have and returns a shopping list for your pet or pets. PLAN FOR THIS FUNCTION: determine the word for a single kind of the animal. if the input is "mice", then we want the output to contain "mouse" (don't worry about any other unusual plurals). Otherwise, look for words that end with "es" and remove the final "es", so "foxes" goes to "fox". Otherwise, remove a final "s". Otherwise, assume that the word is singular. build and return a shopping list, which will be a list of strings. shopping lists should be in the shape: ["mouse food", "mouse treats", "mouse bed", "mouse house"] Sample calls should look like: >>> pet_shopping list("mice") I'mouse food', 'mouse treats',…if L1={ab,b} L2={abb,bb} then LIL2= * O {ababb,abbb,abbab,bbab} O {ab,b,abb,bb} O {ababb,abbb,babb,bbb} O {abbab,abbb,bbab,bbb}struct insert_into_hash_table { // Function takes a constant Book as a parameter, inserts that book indexed by // the book's ISBN into a hash table, and returns nothing. void operator()(const Book& book) { ///// /// TO-DO (8) ||||. // Write the lines of code to insert the key (book's ISBN) and value // ("book") pair into "my_hash_table". /// END-TO-DO (8) // } std::unordered_map& my_hash_table; };
- The setting: Daily Winners An arcade owner asks you for a program to help them out. They want to increase interest in daily high score winners at each of their arcade game machines, so at the end of every day they want and to publish a list of players who have gotten the highest score on that game. They also want to give a prize to the player who has gotten the most high scores on different machines for the day. Your program should give a prize to that player - if no one has gotten more than one high score, choose a winner from the winner's list randomly. Write a function that takes in a list of scores from an arcade machine: [[1, 5, 3, 8, 3], [20, 5], [16, 17, 18]] And a list of players: ["Rahim", "Avano", "Louisa"] The first set of scores in the list of scores belongs to the first player in the list of players, the second list of scores to the second player in the list of players, and so on. Your function should sum each players' list of scores, and add the player with the highest…In c++ The Fibonacci numbers are a series of numbers that exhibit the following pattern: 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, … The series starts with 0 and 1, and each subsequent number in the series is the sum of the previous two numbers. The Fibonacci sequence, Fn, is defined by the following recurrence relation: Fn = Fn-1 + Fn-2 Where the initial values are F0 = 0 and F1 = 1. Write a program that prompts the user to enter in a positive integer N and generates the Nth Fibonacci number. Your main function should handle user input and pass that data to a function called Fib that takes integer N as input and returns the Nth Fibonacci number. Include the functions preconditions and postconditions as comments in your source code. Include some basic input validation to make sure the function’s preconditions are met before the function is called. Show your source code and a sample of your program output.please go in to the detail and explain the purpose and function to each line & function of code listed below.
