2271 - Maximum White Tiles Covered by a Carpet.

Medium

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.

Example 1:

Input: tiles = [[1,5],[10,11],[12,18],[20,25],[30,32]], carpetLen = 10

Output: 9

Explanation: Place 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.

Example 2:

Input: tiles = [[10,11],[1,1]], carpetLen = 2

Output: 2

Explanation: Place the carpet starting on tile 10.

It covers 2 white tiles, so we return 2.

Constraints:

• 1 <= tiles.length <= 5 * 104
• tiles[i].length == 2
• 1 <= li <= ri <= 109
• 1 <= carpetLen <= 109
• The tiles are non-overlapping.
