+# Perl Weekly Challenge Week 197, Task 1 Move Zero
+#
+# You are given a list of integers, @list.
+# Write a script to move all zero, if exists, to the end while maintaining
+# the relative order of non-zero elements.
+# Example 1 Input: @list = (1, 0, 3, 0, 0, 5)
+# Output: (1, 3, 5, 0, 0, 0)
+# Example 2 Input: @list = (1, 6, 4)
+# Output: (1, 6, 4)
+# Example 3 Input: @list = (0, 1, 0, 2, 0
+# Output: (1, 2, 0, 0, 0)
+#
