# Task 1: Monotonic Array
# Submitted by: Mohammad S Anwar
# 
# You are given an array of integers.
# Write a script to find out if the given array is Monotonic. Print 1 if it is otherwise 0.
# 
#     An array is Monotonic if it is either monotone increasing or decreasing.
# 
# Monotone increasing: for i <= j , nums[i] <= nums[j]
# Monotone decreasing: for i <= j , nums[i] >= nums[j]
# 
# Example 1
# Input: @nums = (1,2,2,3)
# Output: 1
# 
# Example 2
# Input: @nums (1,3,2)
# Output: 0
# 
# Example 3
# Input: @nums = (6,5,5,4)
# Output: 1
