+
+Submitted by: [52]Mohammad Sajid Anwar
+     __________________________________________________________________
+
+   You are given a string, $str and a character $char.

+Example 1
+
+Input: $str = "perl", $char = "e"
+Output: 25
+
+Example 2
+
+Input: $str = "java", $char = "a"
+Output: 50
+
+Example 3
+
+Input: $str = "python", $char = "m"
+Output: 0
+
+Example 4
+
+Input: $str = "ada", $char = "a"
