#+ANKI_DECK: study_deck_02 * TODO 0300. Longest Increasing Subsequence :medium: :PROPERTIES: :NEETCODE: [[file:../../roadmap.org::*0300. Longest Increasing Subsequence][0300. Longest Increasing Subsequence]] :END: Given an integer array ~nums~, return /the length of the longest *strictly increasing *//*subsequence*/. *Example 1:* #+begin_src Input: nums = [10,9,2,5,3,7,101,18] Output: 4 Explanation: The longest increasing subsequence is [2,3,7,101], therefore the length is 4. #+end_src *Example 2:* #+begin_src Input: nums = [0,1,0,3,2,3] Output: 4 #+end_src *Example 3:* #+begin_src Input: nums = [7,7,7,7,7,7,7] Output: 1 #+end_src *Constraints:* - ~1 <= nums.length <= 2500~ - ~-10^{4} <= nums[i] <= 10^{4}~ Follow up: Can you come up with an algorithm that runs in ~O(n log(n))~ time complexity? ** TODO Approach Write your approach here. ** TODO Python #+begin_src python class Solution: def lengthOfLIS(self, nums: List[int]) -> int: #+end_src ** TODO C++ #+begin_src cpp class Solution { public: int lengthOfLIS(vector& nums) { } }; #+end_src
