You are given an array of integers nums. Return the length of the longest subarray of nums which is either strictly increasing or strictly decreasing.
\n
Example 1:
\n\nInput: nums = [1,4,3,3,2]
\n\nOutput: 2
\n\nExplanation:
\n\nThe strictly increasing subarrays of nums are [1], [2], [3], [3], [4], and [1,4].
The strictly decreasing subarrays of nums are [1], [2], [3], [3], [4], [3,2], and [4,3].
Hence, we return 2.
Example 2:
\n\nInput: nums = [3,3,3,3]
\n\nOutput: 1
\n\nExplanation:
\n\nThe strictly increasing subarrays of nums are [3], [3], [3], and [3].
The strictly decreasing subarrays of nums are [3], [3], [3], and [3].
Hence, we return 1.
Example 3:
\n\nInput: nums = [3,2,1]
\n\nOutput: 3
\n\nExplanation:
\n\nThe strictly increasing subarrays of nums are [3], [2], and [1].
The strictly decreasing subarrays of nums are [3], [2], [1], [3,2], [2,1], and [3,2,1].
Hence, we return 3.
