Task 1: Unique Number
Submitted by: [45]Mohammad Sajid Anwar
__________________________________________________________________
You are given an array of integers, @ints, where every elements appears
more than once except one element.
Write a script to find the one element that appears exactly one time.
Example 1
Input: @ints = (3, 3, 1)
Output: 1
Example 2
Input: @ints = (3, 2, 4, 2, 4)
Output: 3
Example 3
Input: @ints = (1)
Output: 1
Example 4
Input: @ints = (4, 3, 1, 1, 1, 4)
Output: 3
