6.21 LAB: Permutation and Combination Write two functions called permutation and combination0. where permutation0 computes and returns n! n-r)! whereas combination0 returns n! n -r)r! A third function called par.input0 gets the input values for n and r An example of correct program behavior follows: Input: 3 2 Output: The permutation is 6, and the combination is 3
