+Is Monotonic
+
+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.
