Build a Prefix Sum Array

The array {2, 4, 6, 8} is given. Build a new array where each position holds the running total of all elements up to and including that index, then print it on one line separated by single spaces:

2 6 12 20

Position 0 is 2, position 1 is 2+4=6, position 2 is 2+4+6=12, and position 3 is 2+4+6+8=20.

Expected Output:

2 6 12 20
