Assume there is a function 'swap(int[] nums, int i, int j) that swap the element at index i and the element at index j in the given array.

For example, for nums={1,2,3}.
swap(nums, 0, 1) will change it to {2,1,3}.
swap(nums, 0, 2) will change it to {3,2,1}.

Suppose an int array nums = {10, 20, 30, 40}. How would it change after the following code?
