Dynamic Programming Solutions for Subsequence Problems: Longest Increasing Subsequence, Longest Continuous Increasing Subsequence, and Longest Common Subarray
Longest Increasing Subsequence (LIS)
Problem: Given an unsorted array, find the length of the longest increasing subsequence.
Dynamic Programming Approach:
Define DP array: Let lis[i] represent the length of the longest increasing subsequence ending at index i.
Transition: For each i, iterate through all j < i, and if nums[i] > nums[j], ...
