In this video, we solve LeetCode 2573 Find the String with LCP using a clever greedy construction and verification approach. Learn how to parse the Longest Common Prefix matrix to build the alphabetically smallest string possible in O(n²) time. We break down the two-step pattern of grouping characters from 'a' to 'z' and validating the 2D grid backwards to ensure our candidate string perfectly matches every rule. Whether you are prepping for technical coding interviews or mastering string manipulation and dynamic programming concepts, this step-by-step tutorial provides clear visual explanations and optimized code solutions in Python, Java, C++, and JavaScript.
