Prefix sum
Your task
Given a list of integers nums, return its running (prefix) sum: a list of the same length where result[i] equals the sum of nums[0..i] inclusive. For example [1, 2, 3, 4] becomes [1, 3, 6, 10]. The list may be empty (return []).
Examples
running_sum(nums: list[int]) -> list[int]Example 1
Input
running_sum([1, 2, 3, 4])Output
[1, 3, 6, 10]
