Longest Increasing Subsequence
Given an integer array nums, return the length of the longest strictly increasing subsequence.
Follow up: Can you come up with an algorithm that runs in O(n log(n)) time complexity?
Example 1
Input
nums = [10,9,2,5,3,7,101,18]Output
4The longest increasing subsequence is [2,3,7,101], therefore the length is 4.
Example 2
Input
nums = [0,1,0,3,2,3]Output
4The longest increasing subsequence has length 4.
Constraints
- 1 <= nums.length <= 2500
- -10^4 <= nums[i] <= 10^4
