Given an array nums. We define a running sum of an array as runningSum[i] = sum(nums[0]…nums[i]).

\r\n\r\n

Return the running sum of nums.

\r\n\r\n

 

\r\n

Example 1:

\r\n\r\n
\r\nInput: nums = [1,2,3,4]\r\nOutput: [1,3,6,10]\r\nExplanation: Running sum is obtained as follows: [1, 1+2, 1+2+3, 1+2+3+4].
\r\n\r\n

Example 2:

\r\n\r\n
\r\nInput: nums = [1,1,1,1,1]\r\nOutput: [1,2,3,4,5]\r\nExplanation: Running sum is obtained as follows: [1, 1+1, 1+1+1, 1+1+1+1, 1+1+1+1+1].
\r\n\r\n

Example 3:

\r\n\r\n
\r\nInput: nums = [3,1,2,10,1]\r\nOutput: [3,4,6,16,17]\r\n
