Hey students! If you’re exploring recursion and backtracking, this problem is a great follow-up to subsets or subsequences. It’s like the “Subsets with Sum K” but simpler, instead of finding all, we just check if at least one exists. We’ll use backtracking to explore possibilities, and I’ll explain it in easy terms so you can grasp how it works. Remember, this is for learning recursion, so we’ll focus on the concept even if it’s not the fastest … Continue reading Check if there exists a subsequence with sum = K | Backtracking Solution in Python
