Two images A and B are given, represented as binary, square matrices of the same size.  (A binary matrix has only 0s and 1s as values.) We translate one image however we choose (sliding it left, right, up, or down any number of units), and place it o…

A rectangle is represented as a list [x1, y1, x2, y2], where (x1, y1) are the coordinates of its bottom-left corner, and (x2, y2) are the coordinates of its top-right corner. Two rectangles overlap if the area of their intersection is positive.  To b…

835. 图像重叠 给出两个图像 A 和 B ,A 和 B 为大小相同的二维正方形矩阵.(并且为二进制矩阵,只包含0和1). 我们转换其中一个图像,向左,右,上,或下滑动任何数量的单位,并把它放在另一个图像的上面.之后,该转换的重叠是指两个图像都具有 1 的位置的数目. (请注意,转换不包括向任何方向旋转.) 最大可能的重叠是什么? 示例 1: 输入:A = [[1,1,0], [0,1,0], [0,1,0]] B = [[0,0,0], [0,1,1], [0,0,1]] 输出:3 解释:…

Given a collection of intervals, find the minimum number of intervals you need to remove to make the rest of the intervals non-overlapping. Note: You may assume the interval's end point is always bigger than its start point. Intervals like [1,2] and…

1.题目描述 给定一个二进制矩阵 A,我们想先水平翻转图像,然后反转图像并返回结果. 水平翻转图片就是将图片的每一行都进行翻转,即逆序.例如,水平翻转 [1, 1, 0] 的结果是 [0, 1, 1]. 反转图片的意思是图片中的 0 全部被 1 替换, 1 全部被 0 替换.例如,反转 [0, 1, 1] 的结果是 [1, 0, 0]. 示例 1: 输入: [[,,],[,,],[,,]] 输出: [[,,],[,,],[,,]] 解释: 首先翻转每一行: [[,,],[,,],[,,]]: 然…

836. 矩形重叠 矩形以列表 [x1, y1, x2, y2] 的形式表示,其中 (x1, y1) 为左下角的坐标,(x2, y2) 是右上角的坐标. 如果相交的面积为正,则称两矩形重叠.需要明确的是,只在角或边接触的两个矩形不构成重叠. 给出两个矩形,判断它们是否重叠并返回结果. 示例 1: 输入:rec1 = [0,0,2,2], rec2 = [1,1,3,3] 输出:true 示例 2: 输入:rec1 = [0,0,1,1], rec2 = [1,0,2,1] 输出:false 提示…

A rectangle is represented as a list [x1, y1, x2, y2], where (x1, y1) are the coordinates of its bottom-left corner, and (x2, y2) are the coordinates of its top-right corner. Two rectangles overlap if the area of their intersection is positive. To be…

［抄题］: A rectangle is represented as a list [x1, y1, x2, y2], where (x1, y1) are the coordinates of its bottom-left corner, and (x2, y2) are the coordinates of its top-right corner. Two rectangles overlap if the area of their intersection is positive.…

题目: 有一幅以二维整数数组表示的图画,每一个整数表示该图画的像素值大小,数值在 0 到 65535 之间. An image is represented by a 2-D array of integers, each integer representing the pixel value of the image (from 0 to 65535). 给你一个坐标 (sr, sc) 表示图像渲染开始的像素值(行 ,列)和一个新的颜色值 newColor,让你重新上色这幅图像. Given…
