Question

Problem: Zipper For this problem, you have some starter code. Save it and run it a few times -- you will see that it generates two arrays of equal lengths populated with random values in range [0,9]. Your task is to complete the zip() method, which takes two equal length arrays and "zips" them. See sample runs below and comments in the starter code for further description of what that means. Input Validation: • None - there is no user input. Requirements: . Do not change anything in the starter code other than the body of the zip () method. (Although you may add helper methods if you want.)
