Leetcode Problem 2070: Most Beautiful Item for Each Query | C++ Solution Explained
In this video, we tackle Leetcode Problem 2070: "Most Beautiful Item for Each Query." This medium-level problem involves finding the maximum beauty of items under a price threshold for each query, using an efficient C++ approach with binary search and sorting. We’ll go step-by-step through the code, explaining concepts such as sorting, custom comparison functions, and binary search for optimal solution performance.
📝 Problem Outline
Given a list of items where each has a price and beauty score, and a list of price queries, we need to return the highest possible beauty for each query without exceeding the query price.
🚀 Solution Approach
Custom Sorting: We sort items by price in ascending order, and by beauty in descending order for items with the same price.
Binary Search: For each query, use binary search to find the item with the maximum beauty under the given price.
Complexity Optimization: We discuss the solution’s time complexity (O(N log N + M log N)) and space complexity (O(M)), where N is the number of items and M is the number of queries.
