+# Task 2: Digit Count Value
+# Submitted by: 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.
