Task 1: Running Sum

Submitted by: [43]Mohammad S Anwar
     __________________________________________________________________

   You are given an array of integers.

   Write a script to return the running sum of the given array. The
   running sum can be calculated as sum[i] = num[0] + num[1] + …. +
   num[i].

Example 1

Input: @int = (1, 2, 3, 4, 5)
Output: (1, 3, 6, 10, 15)

Example 2

Input: @int = (1, 1, 1, 1, 1)
Output: (1, 2, 3, 4, 5)

Example 3

Input: @int = (0, -1, 1, 2)
Output: (0, -1, 0, 2)
