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 (see Expected Output).

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↵

= newline. The output ends with a newline — print one after the last line.
