3213. Construct String with Minimum Cost | Weekly Leetcode 405 | Trie + DP

Hi, I am Amit Dhyani. Today, we solve a problem from LeetCode's Weekly Contest 405.

3213. Construct String with Minimum Cost

*********************************************
In this video, I begin by explaining the brute force approach, identifying the mistakes and inefficiencies in this method. Next, I introduce the prefix tree (Trie) and demonstrate how it improves upon the brute force approach, explaining its functionality and benefits. Finally, I show how to further optimize the solution using the prefix tree for better performance.

Let's dive into the journey from brute force solution to optimised solution.
