+# Task 1: Max Positive Negative
+# Submitted by: Mohammad Sajid Anwar
+# 
+# You are given an array of integers, @ints.
+# Write a script to return the maximum number of either positive or negative integers in the given array.
+# 
+# Example 1
+# Input: @ints = (-3, 1, 2, -1, 3, -2, 4)
+# Output: 4
+# 
+# Count of positive integers: 4
+# Count of negative integers: 3
+# Maximum of count of positive and negative integers: 4
+# 
+# Example 2
+# Input: @ints = (-1, -2, -3, 1)
+# Output: 3
+# 
+# Count of positive integers: 1
+# Count of negative integers: 3
+# Maximum of count of positive and negative integers: 3
+# 
+# Example 3
+# Input: @ints = (1,2)
+# Output: 2
+# 
+# Count of positive integers: 2
+# Count of negative integers: 0
+# Maximum of count of positive and negative integers: 2
