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
