+# Task 1: Smaller than Current
+# Submitted by: Mohammad Sajid Anwar
+# 
+# You are given a array of integers, @ints.
+# Write a script to find out how many integers are smaller than current i.e. foreach ints[i], count ints[j] < ints[i] where i != j.
+# 
+# Example 1
+# Input: @ints = (5, 2, 1, 6)
+# Output: (2, 1, 0, 3)
+# 
+# For $ints[0] = 5, there are two integers (2,1) smaller than 5.
+# For $ints[1] = 2, there is one integer (1) smaller than 2.
+# For $ints[2] = 1, there is none integer smaller than 1.
+# For $ints[3] = 6, there are three integers (5,2,1) smaller than 6.
+# 
+# Example 2
+# Input: @ints = (1, 2, 0, 3)
+# Output: (1, 2, 0, 3)
+# 
+# Example 3
+# Input: @ints = (0, 1)
+# Output: (0, 1)
+# 
+# Example 4
+# Input: @ints = (9, 4, 9, 2)
+# Output: (2, 1, 2, 0)
