swap

Language/Type: Java arrays reference semantics
Author: Marty Stepp (on 2010/12/28)

Write a method named swap that accepts an arrays of integers and two indexes as its parameters and swaps the elements at those indexes. You may assume that the array passed is not null and that the indexes are within the bounds of the array.

For example, if the following parameters are passed: 

int[] a = {11, 42, -5, 27, 0, 89};
swap(a, 1, 3);

After the call, the array a should store the elements {11, 27, -5, 42, 0, 89}.
