You are given an m x n binary matrix grid where each cell is either 0 (empty) or 1 (occupied).
You are then given stamps of size stampHeight x stampWidth. We want to fit the stamps such that they follow the given restrictions and requirements:
Return true if it is possible to fit the stamps while following the given restrictions and requirements. Otherwise, return false.
\n
Example 1:
\n\n\nInput: grid = [[1,0,0,0],[1,0,0,0],[1,0,0,0],[1,0,0,0],[1,0,0,0]], stampHeight = 4, stampWidth = 3\nOutput: true\nExplanation: We have two overlapping stamps (labeled 1 and 2 in the image) that are able to cover all the empty cells.\n\n\n
Example 2:
\n![\"\"](\"https://assets.leetcode.com/uploads/2021/11/03/ex2.png\")
\n\nInput: grid = [[1,0,0,0],[0,1,0,0],[0,0,1,0],[0,0,0,1]], stampHeight = 2, stampWidth = 2 \nOutput: false \nExplanation: There is no way to fit the stamps onto all the empty cells without the stamps going outside the grid.\n\n\n
\n
Constraints:
\n\nm == grid.lengthn == grid[r].length1 <= m, n <= 1051 <= m * n <= 2 * 105grid[r][c] is either 0 or 1.1 <= stampHeight, stampWidth <= 105给你一个 m x n 的二进制矩阵 grid ，每个格子要么为 0 （空）要么为 1 （被占据）。
给你邮票的尺寸为 stampHeight x stampWidth 。我们想将邮票贴进二进制矩阵中，且满足以下 限制 和 要求 ：
如果在满足上述要求的前提下，可以放入邮票，请返回 true ，否则返回 false 。
\n\n
示例 1：
\n\n
输入：grid = [[1,0,0,0],[1,0,0,0],[1,0,0,0],[1,0,0,0],[1,0,0,0]], stampHeight = 4, stampWidth = 3\n输出：true\n解释：我们放入两个有重叠部分的邮票（图中标号为 1 和 2），它们能覆盖所有与空格子。\n\n\n
示例 2：
\n\n
输入：grid = [[1,0,0,0],[0,1,0,0],[0,0,1,0],[0,0,0,1]], stampHeight = 2, stampWidth = 2 \n输出：false \n解释：没办法放入邮票覆盖所有的空格子，且邮票不超出网格图以外。\n\n\n
\n\n
提示：
\n\nm == grid.lengthn == grid[r].length1 <= m, n <= 1051 <= m * n <= 2 * 105grid[r][c] 要么是 0 ，要么是 1 。1 <= stampHeight, stampWidth <= 105\\u7248\\u672c\\uff1a
