🔍 LeetCode 2900 - Longest Unequal Adjacent Groups Subsequence | C++ Recursion Solution Explained

In this video, we solve LeetCode Problem 2900: Longest Unequal Adjacent Groups Subsequence I using a clean C++ recursive approach. 💡 📌 Problem Summary: You're given two arrays: words (strings) groups (integers) Your goal is to return the longest subsequence of words where no two adjacent words belong to the same group. 🎯 What You’ll Learn in This Video: How to think recursively for subsequence problems Edge cases and correct index management in C++ Optimization tips for interview-style problems 🧠 Approach: We build a result list recursively by checking whether adjacent groups are different — only then do we include the word in the result. 📘 C++ Topics Covered: Vectors Recursion Condition checking Clean code structure for interviews ✅ Don't forget to: 👍 Like 🔔 Subscribe 📝 Comment if you want the iterative version! #LeetCode2900 #C++ #Recursion #CodingInterview #DSA #LeetCode #SubsequenceProblem
