+Task 1: Sort String
+
+Submitted by: [51]Mohammad Sajid Anwar
+     __________________________________________________________________
+
+   You are given a shuffle string, $str.
+
+   Write a script to return the sorted string.
+
+     A string is shuffled by appending word position to each word.
+
+Example 1
+
+Input: $str = "and2 Raku3 cousins5 Perl1 are4"
+Output: "Perl and Raku are cousins"
+
+Example 2
+
+Input: $str = "guest6 Python1 most4 the3 popular5 is2 language7"
+Output: "Python is the most popular guest language"
+
+Example 3
+
+Input: $str = "Challenge3 The1 Weekly2"
+Output: "The Weekly Challenge"
+
+Task 2: Reverse Word
