Given an integer array nums, return the length of the longest strictly increasing subsequence.

\n\n

A subsequence is a sequence that can be derived from an array by deleting some or no elements without changing the order of the remaining elements. For example, [3,6,2,7] is a subsequence of the array [0,3,1,6,2,2,7].

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [10,9,2,5,3,7,101,18]\nOutput: 4\nExplanation: The longest increasing subsequence is [2,3,7,101], therefore the length is 4.\n
\n\n

Example 2:

\n\n
\nInput: nums = [0,1,0,3,2,3]\nOutput: 4\n
\n\n

Example 3:

\n\n
\nInput: nums = [7,7,7,7,7,7,7]\nOutput: 1\n
\n\n

Follow up: Can you come up with an algorithm that runs in O(n log(n)) time complexity?
