+# Task 2: Reverse Prefix
+# Submitted by: Mohammad Sajid Anwar
+# 
+# You are given a string, $str and a character in the given string, $char.
+# Write a script to reverse the prefix upto the first occurrence of the given $char in the given string $str and return the new string.
+# 
+# Example 1
+# Input: $str = "programming", $char = "g"
+# Output: "gorpmming"
+# 
+# Reverse of prefix "prog" is "gorp".
+# 
+# Example 2
+# Input: $str = "hello", $char = "h"
+# Output: "hello"
+# 
+# Example 3
+# Input: $str = "abcdefghij", $char = "h"
+# Output: "hgfedcbaj"
+# 
+# Example 4
+# Input: $str = "reverse", $char = "s"
+# Output: "srevere"
+# 
+# Example 5
+# Input: $str = "perl", $char = "r"
+# Output: "repl"
