+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

+
+Submitted by: [46]Mohammad Sajid Anwar
+     __________________________________________________________________
+
+   You are given an array of positive integers, @ints.
+
+   Write a script to return true if for every index i in the range 0 <= i
+   < size of array, the digit i occurs exactly the $ints[$i] times in the
+   given array otherwise return false.
+
+Example 1
+
+Input: @ints = (1, 2, 1, 0)
+Ouput: true
+
+$ints[0] = 1, the digit 0 occurs exactly 1 time.
+$ints[1] = 2, the digit 1 occurs exactly 2 times.
+$ints[2] = 1, the digit 2 occurs exactly 1 time.
+$ints[3] = 0, the digit 3 occurs 0 time.
+
+Example 2
+
+Input: @ints = (0, 3, 0)
+Ouput: false
+
+$ints[0] = 0, the digit 0 occurs 2 times rather than 0 time.
+$ints[1] = 3, the digit 1 occurs 0 time rather than 3 times.
+$ints[2] = 0, the digit 2 occurs exactly 0 time.
