leetcode/0896_monotonic-array

An array is monotonic if it is either monotone increasing or monotone decreasing.

An array nums is monotone increasing if for all i <= j, nums[i] <= nums[j]. An array nums is monotone decreasing if for all i <= j, nums[i] >= nums[j].

Given an integer array nums, return true_if the given array is monotonic, or _falseotherwise.

Example 1:

Input: nums = [1,2,2,3] Output: true 

Example 2:

Input: nums = [6,5,4,4] Output: true 

Example 3:

Input: nums = [1,3,2] Output: false 

Constraints:

• 1 <= nums.length <= 105
• -105 <= nums[i] <= 105
