Difference Between Element Sum and Digit Sum of an Array
You are given a positive integer array nums.
- The element sum is the sum of all the elements in
nums. - The digit sum is the sum of all the digits (not necessarily distinct) that appear in
nums.
Return the absolute difference between the element sum and digit sum of nums.
Note that the absolute difference between two integers x and y is defined as |x - y|.
Example 1
Input
nums = [1,15,6,3]Output
9The element sum is 25, the digit sum is 16, and the absolute difference is 9.
Example 2
Input
nums = [1,2,3,4]Output
0The element sum is 10, the digit sum is 10, and the absolute difference is 0.
Constraints
- 1 <= nums.length <= 2000
- 1 <= nums[i] <= 2000
