Grokking the Coding Interview Patterns in C++

Longest Increasing Subsequence

Explore how to determine the longest increasing subsequence in an integer array, understanding problem constraints and optimizing with O(nlogn) time complexity. This lesson helps you apply fundamental coding interview patterns to efficiently solve and implement solutions in C++.

We'll cover the following...

Statement

The Longest Increasing Subsequence (LIS) is the longest subsequence from a given array in which the subsequence elements are sorted in a strictly increasing order. Given an integer array, nums, find the length of the LIS in this array.

Constraints:

  • 1≤1 \leq
