+# Task 1: Target Index
+# Submitted by: 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
