+Task 2: Duplicate Zeros
+
+Submitted by: [45]Mohammad S Anwar
+     __________________________________________________________________
+
+   You are given an array of integers.
+
+   Write a script to duplicate each occurrence of ZERO in the given array
+   and shift the remaining to the right but make sure the size of array
+   remain the same.
+
+Example 1
+
+Input: @ints = (1, 0, 2, 3, 0, 4, 5, 0)
+Ouput: (1, 0, 0, 2, 3, 0, 0, 4)
+
+Example 2
+
+Input: @ints = (1, 2, 3)
+Ouput: (1, 2, 3)
+
+Example 3
+
+Input: @ints = (0, 3, 0, 4, 5)
+Ouput: (0, 0, 3, 0, 0)
