To multiply two positive integers without using the * operator (or / operator), use a recursive function. Bit shifting, addition, and subtraction are all acceptable, but you should use them sparingly.

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.

Using C write a program that uses a recursive function to find the  greatest common divisor  of two integers provided by the user. Example behavior: ./gcd Enter x: 24 Enter y: 32 The GCD of 24 and 32 is 8

1.)I have to recursive with python language and was asked to do a buy 2 get 1 free where you have some amount of money(x) each item costs a given amount(y), for each 2 item you get 1 free, builda recursive solution to find out how many items you can buy for x amount of money. 2.) Buy M, get N free Then alter your first answer to allow for the user to enter any M and N for how many you need to buy to get free items
