Understanding the Maximum White Tiles Covered by a Carpet Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a 2D integer array tiles where tiles[i] = [li, ri] represents that every tile j in the range li <= j <= ri is colored white. You are also given an integer carpetLen, the length of a single carpet that can be placed anywhere. Return the maximum number of white tiles that can be covered by the carpet.

Get real-time assistance for Maximum White Tiles Covered by a Carpet problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
tiles = [[1,5],[10,11],[12,18],[20,25],[30,32]], carpetLen = 109Place the carpet starting on tile 10. It covers 9 white tiles, so we return 9. Note that there may be other places where the carpet covers 9 white tiles. It can be shown that the carpet cannot cover more than 9 white tiles.
tiles = [[10,11],[1,1]], carpetLen = 22Place the carpet starting on tile 10. It covers 2 white tiles, so we return 2.
Constraints
1 <= tiles.length <= 5 * 104tiles[i].length == 21 <= li <= ri <= 1091 <= carpetLen <= 109The tiles are non-overlapping.How Interview Coder Helps with Leetcode Problems
