Objective

Write a function that fills a separate output buffer with the running totals of an integer array, one total per element.

Steps

• a points to the n integers to read, and out points to a buffer with room for n values of type long.
• Set out[i] to the sum of a[0] through a[i] included, so out[0] equals a[0] and out[i] equals out[i - 1] + a[i].
• Write exactly n values into out, never more.
• Treat a as read-only. Never write through it.
• When n is 0, leave out untouched and return.
• The output type is long because the running total can outgrow an int even when every single element fits in one. Widen to long before you add, not after.
• The checker prints the values of out on one line, separated by a single space, with a trailing newline.
