In an array, we can swap the elements at any two indices in a single operation called a move. For example, if our array is a = {17, 4, 8}, we can swap a0 = 17 and a2 = 8 to get a = {8,4,17} in a single move. We want to custom-sort an array such that all of the even elements are at the beginning of the array and all of the odd elements are at the end of the array. Complete the function moves.
