2 * [1480] Running Sum of 1d Array
3 *
4 * Given an array nums. We define a running sum of an array as runningSum[i] = sum(nums[0]…nums[i]).
5 * 
6 * Return the running sum of nums.
7 * 
8 *  
9 * Example 1:
10 * 
11 * 
12 * Input: nums = [1,2,3,4]
13 * Output: [1,3,6,10]
14 * Explanation: Running sum is obtained as follows: [1, 1+2, 1+2+3, 1+2+3+4].
15 * 
16 * Example 2:
17 * 
18 * 
19 * Input: nums = [1,1,1,1,1]
20 * Output: [1,2,3,4,5]
21 * Explanation: Running sum is obtained as follows: [1, 1+1, 1+1+1, 1+1+1+1, 1+1+1+1+1].
22 * 
23 * Example 3:
24 * 
25 * 
26 * Input: nums = [3,1,2,10,1]
27 * Output: [3,4,6,16,17]
28 * 
29 * 
30 *  
31 * Constraints:
32 * 
33 * 
34 * 	1 <= nums.length <= 1000
35 * 	-10^6 <= nums[i] <= 10^6
36 *
