+# Task 1: Odd Character
+# Submitted by: Mohammad Sajid Anwar
+# 
+# You are given two strings, $s and $t. The string $t is generated using the shuffled characters of the string $s with an additional character.
+# Write a script to find the additional character in the string $t..
+# 
+# Example 1
+# Input: $s = "Perl" $t = "Preel"
+# Output: "e"
+# 
+# Example 2
+# Input: $s = "Weekly" $t = "Weeakly"
+# Output: "a"
+# 
+# Example 3
+# Input: $s = "Box" $t = "Boxy"
+# Output: "y"
