Array Sum Modulo 10 | Dataford Interview Questions

Return the sum modulo 10 from an array of integers.

Implement sum_mod_10(nums), where nums is a non-empty list of integers. Return the remainder of the total sum divided by 10. The result should follow Python's modulo behavior, so it is always an integer from 0 through 9.

Input: A list of integers.

Output: One integer representing sum(nums) % 10.

Constraints

1 <= nums.length <= 1000
-10^9 <= nums[i] <= 10^9
Return an integer from 0 through 9

Function Signature
