- Modify the recursive Fibonacci function to employ the memoization technique discussed in this chapter. The function creates a dictionary and then defines a nested recursive helper function named memoizedFib. You will need to create a dictionary to cache the sum of the fib function. The base case of the fib function is the same as before. However, before making any recursive calls, the helper function looks up the value for the function’s current argument in the dictionary (use the method get, with None as the default value). If the value exists, the function returns it and skips any recursive calls. Otherwise, after the helper function adds the results of its two recursive calls, it saves the sum in the dictionary with the current argument of the function as the key. Note: The program should output in the following format: n fib(n) 2 1 4 3 8 21 16 987 32 2178309 ---------------------------------------------------------------------------------- def…4.10 LAB: All permutations of names Write a program that lists all ways people can line up for a photo (all permutations of a list of strings). The program will read a list of one word names, then use a recursive function to create and output all possible orderings of those names separated by a comma, one ordering per line. When the input is: Julia Lucas Mia then the output is (must match the below ordering): Julia, Lucas, Mia Julia, Mia, Lucas Lucas, Julia, Mia Lucas, Mia, Julia Mia, Julia, Lucas Mia, Lucas, Julia def print_all_permutations(permList, nameList): # TODO: Implement method to create and output all permutations of the list of names. if __name__ == "__main__": nameList = input().split(' ') permList = [] print_all_permutations(permList, nameList)def removeMultiples(x, arr) - directly remove the multiples of prime numbers (instead of just marking them) by creating a helper function.

- One-friend recursion vs iteration. 1. Your objective is to receive the tuple a1, a2,..., a and return the tuple an, an1,..., a1 that has been inverted. You will only take an element off of one end or put an element back on one end because you are being lazy. But you have friends in recursion who can assist you.Please provide the recursive code as well as a paragraph with the friend's description of the algorithm.2. Now imagine that you lack friends but have a stack. Quickly design an iterative programme to address this issue. Include loop invariants and other crucial stages that are necessary to describe an iterative method.3. Trace both of these scripts separately. On a computer, step by step compare and contrast their calculations.Write a recursive function to sort an array of integers into ascending order using the following idea: the function must place the smallest element in the first position, then sort the rest of the array by a recursive call. This is a recursive version of the selection sort. (Note: You will probably want to call an auxiliary function that finds the index of the smallest item in the array. Make sure that the sorting function itself is recursive. Any auxiliary function that you use may be either recursive or iterative.) Embed your sort function in a driver program to test it. Turn in the entire program and the output.In python. Please include docstring, and follow code style requirements below. Write a recursive function named is_decreasing that takes as its parameter a list of numbers. It should return True if the elements of the list are strictly decreasing but return False otherwise. Strictly decreasing means that each element is less than the preceding one - not less than or equal. You can assume the array contains at least two elements. You may use default arguments and/or helper functions. Your recursive function must not: use any loops use any variables declared outside of the function use any mutable default arguments (see the Code Style Requirements)
- In python. Please include docstring, and follow the code style requirements below. Thanks. Write a recursive function named list_max that takes as its parameter a list of numbers and returns the maximum value in the list. You can assume the list contains at least one element. If multiple elements of the list are tied for the maximum, you would still return that value. You cannot call the built-in max() function. You may use default arguments and/or helper functions. Your recursive function must not: use any loops use any variables declared outside of the function use any mutable default arguments (see the Code Style Requirements)C++ (a) Use iteration (b) Use recursion (c) Convert the function that you wrote in part (b) into a template function. The template function should work for arrays of any type.Write a recursive function that adds all the elements in an array. The function will take two arguments, 1) An integer value that is greater than 0 and indicates the size of the array, and 2) An integer array of that size. The function should return an integer value that is the sum of the elements in the array. The function should add elements of the input array using recursion and should not use a loop.ii) Read both a string and the key (integer) is entered through the keyboard. Define a function to encrypt each and every character in a string with the given key. As a programmer, implement the same by writing the C code using pointers. If the given Key is positive, then traverse towards left of the character in the Alphabet sequence. Otherwise, move traverse towards the right of the character in the Alphabet sequence. Example : if the given string is "PRADEEP" and Key = 3 then the encrypted string is "SUDGHHS" iii) An ISBN (International Standard Book Number) is a 10 digit number…
- T/F 9. As loop variables and recursive solutions are also not used for iterative solutions, the recursive solution generally makes memorization more effective (use fewer stored) than the corresponding iterative solution.in python. Please include docstring. Write a recursive function named list_max that takes as its parameter a list of numbers and returns the maximum value in the list. You can assume the list contains at least one element. If multiple elements of the list are tied for the maximum, you would still return that value. You cannot call the built-in max() function. You may use default arguments and/or helper functions. Your recursive function must not: use any loops use any variables declared outside of the function use any mutable default arguments (see the Code Style Requirements)PYTHON RECURSIVE FUNCTION Write a python program that lists all ways people can line up for a photo (all permutations of a list of strings).
