In this video, I solve LeetCode Problem #17: Letter Combinations of a Phone Number using Java. This problem is a great introduction to backtracking, where you generate all possible letter combinations from a digit string. I’ll explain the recursive logic clearly and build a clean Java solution with you! ☎️ ✨ What you’ll learn: Mapping digits to letters like a phone keypad Applying backtracking to generate combinations Writing clean, efficient recursive Java code 📌 Problem link: https://leetcode.com/problems/letter-combi... 💬 Have a question or another solution idea?
