Task 1: Element Digit Sum
Submitted by: [45]Mohammad Sajid Anwar
__________________________________________________________________
You are given an array of integers, @ints.
Write a script to evaluate the absolute difference between element and
digit sum of the given array.
Example 1
Input: @ints = (1,2,3,45)
Output: 36
Element Sum: 1 + 2 + 3 + 45 = 51
Digit Sum: 1 + 2 + 3 + 4 + 5 = 15
Absolute Difference: | 51 - 15 | = 36
Example 2
Input: @ints = (1,12,3)
Output: 9
Element Sum: 1 + 12 + 3 = 16
Digit Sum: 1 + 1 + 2 + 3 = 7
Absolute Difference: | 16 - 7 | = 9
Example 3
Input: @ints = (1,2,3,4)
Output: 0
Element Sum: 1 + 2 + 3 + 4 = 10
Digit Sum: 1 + 2 + 3 + 4 = 10
Absolute Difference: | 10 - 10 | = 0
Example 4
Input: @ints = (236, 416, 336, 350)
Output: 1296
Task 2: Multiply by Two
