Task 1: Target Index

Submitted by: [47]Mohammad Sajid Anwar
     __________________________________________________________________

   You are given an array of integers, @ints and a target element $k.

   Write a script to return the list of indices in the sorted array where
   the element is same as the given target element.

Example 1

Input: @ints = (1, 5, 3, 2, 4, 2), $k = 2
Output: (1, 2)

Sorted array: (1, 2, 2, 3, 4, 5)
Target indices: (1, 2) as $ints[1] = 2 and $ints[2] = 2

Example 2

Input: @ints = (1, 2, 4, 3, 5), $k = 6
Output: ()

No element in the given array matching the given target.

Example 3

Input: @ints = (5, 3, 2, 4, 2, 1), $k = 4
Output: (4)

Sorted array: (1, 2, 2, 3, 4, 5)
Target index: (4) as $ints[4] = 4

Task 2: Merge Items
