+Task 1: Defang IP Address
+
+Submitted by: [45]Mohammad Sajid Anwar
+     __________________________________________________________________
+
+   You are given a valid IPv4 address.
+
+   Write a script to return the defanged version of the given IP address.
+
+     A defanged IP address replaces every period “.” with “[.]".
+
+Example 1
+
+Input: $ip = "1.1.1.1"
+Output: "1[.]1[.]1[.]1"
+
+Example 2
+
+Input: $ip = "255.101.1.0"
+Output: "255[.]101[.]1[.]0"

+Task 2: String Score
+
+Submitted by: [46]Mohammad Sajid Anwar
+     __________________________________________________________________
+
+   You are given a string, $str.
+
+   Write a script to return the score of the given string.
+
+     The score of a string is defined as the sum of the absolute
+     difference between the ASCII values of adjacent characters.
+
+Example 1
+
+Input: $str = "hello"
+Output: 13
+
+ASCII values of characters:
+h = 104
+e = 101
+l = 108
+l = 108
+o = 111
+
+Score => |104 - 101| + |101 - 108| + |108 - 108| + |108 - 111|
+      => 3 + 7 + 0 + 3
+      => 13
+
+Example 2
+
+Input: "perl"
+Output: 30
+
+ASCII values of characters:
+p = 112
+e = 101
+r = 114
+l = 108
+
+Score => |112 - 101| + |101 - 114| + |114 - 108|
+      => 11 + 13 + 6
+      => 30
+
+Example 3
+
+Input: "raku"
+Output: 37
+
+ASCII values of characters:
+r = 114
+a = 97
+k = 107
+u = 117
+
+Score => |114 - 97| + |97 - 107| + |107 - 117|
+      => 17 + 10 + 10
+      => 37
