+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 _`false`_otherwise_.
+
+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`
