You are given a positive integer array nums.

\n\n\n\n

Return the absolute difference between the element sum and digit sum of nums.

\n\n

Note that the absolute difference between two integers x and y is defined as |x - y|.

Example 1:

\n\n
\nInput: nums = [1,15,6,3]\nOutput: 9\nExplanation: \nThe element sum of nums is 1 + 15 + 6 + 3 = 25.\nThe digit sum of nums is 1 + 1 + 5 + 6 + 3 = 16.\nThe absolute difference between the element sum and digit sum is |25 - 16| = 9.\n
\n\n

Example 2:

\n\n
\nInput: nums = [1,2,3,4]\nOutput: 0\nExplanation:\nThe element sum of nums is 1 + 2 + 3 + 4 = 10.\nThe digit sum of nums is 1 + 2 + 3 + 4 = 10.\nThe absolute difference between the element sum and digit sum is |10 - 10| = 0.\n
