{ "data": { "question": { "questionId": "2311", "questionFrontendId": "2209", "categoryTitle": "Algorithms", "boundTopicId": 1344851, "title": "Minimum White Tiles After Covering With Carpets", "titleSlug": "minimum-white-tiles-after-covering-with-carpets", "content": "

You are given a 0-indexed binary string floor, which represents the colors of tiles on a floor:

\n\n\n\n

You are also given numCarpets and carpetLen. You have numCarpets black carpets, each of length carpetLen tiles. Cover the tiles with the given carpets such that the number of white tiles still visible is minimum. Carpets may overlap one another.

\n\n

Return the minimum number of white tiles still visible.

\n\n

 

\n

Example 1:

\n\"\"\n
\nInput: floor = "10110101", numCarpets = 2, carpetLen = 2\nOutput: 2\nExplanation: \nThe figure above shows one way of covering the tiles with the carpets such that only 2 white tiles are visible.\nNo other way of covering the tiles with the carpets can leave less than 2 white tiles visible.\n
\n\n

Example 2:

\n\"\"\n
\nInput: floor = "11111", numCarpets = 2, carpetLen = 3\nOutput: 0\nExplanation: \nThe figure above shows one way of covering the tiles with the carpets such that no white tiles are visible.\nNote that the carpets are able to overlap one another.\n
\n\n

Constraints:

\n\n\n", "translatedTitle": "用地毯覆盖后的最少白色砖块", "translatedContent": "

给你一个下标从 0 开始的 二进制 字符串 floor ，它表示地板上砖块的颜色。

\n\n\n\n

同时给你 numCarpets 和 carpetLen 。你有 numCarpets 条 黑色 的地毯，每一条 黑色 的地毯长度都为 carpetLen 块砖块。请你使用这些地毯去覆盖砖块，使得未被覆盖的剩余 白色 砖块的数目 最小 。地毯相互之间可以覆盖。

\n\n

请你返回没被覆盖的白色砖块的 最少 数目。

\n\n

 

\n\n

示例 1：

\n\n

\"\"

\n\n
输入：floor = \"10110101\", numCarpets = 2, carpetLen = 2\n输出：2\n解释：\n上图展示了剩余 2 块白色砖块的方案。\n没有其他方案可以使未被覆盖的白色砖块少于 2 块。\n
\n\n

示例 2：

\n\n

\"\"

\n\n
输入：floor = \"11111\", numCarpets = 2, carpetLen = 3\n输出：0\n解释：\n上图展示了所有白色砖块都被覆盖的一种方案。\n注意，地毯相互之间可以覆盖。\n
