给定在 xy 平面上的一组点,确定由这些点组成的任何矩形的最小面积,其中矩形的边不一定平行于 x 轴和 y 轴. 如果没有任何矩形,就返回 0. 示例 1: 输入:[[1,2],[2,1],[1,0],[0,1]] 输出:2.00000 解释:最小面积的矩形出现在 [1,2],[2,1],[1,0],[0,1] 处,面积为 2. 示例 2: 输入:[[0,1],[2,1],[1,1],[1,0],[2,0]] 输出:1.00000 解释:最小面积的矩形出现在 [1,0],[1,1],[2,1],…

Given a set of points in the xy-plane, determine the minimum area of any rectangle formed from these points, with sides not necessarily parallel to the x and y axes. If there isn't any rectangle, return 0. Example 1: Input: [[1,2],[2,1],[1,0],[0,1]]…

题目标签:HashMap 题目给了我们一组 xy 上的点坐标,让我们找出 能组成矩形里最小面积的那个. 首先遍历所有的点,把x 坐标当作key 存入map, 把重复的y坐标 组成set,当作value 存入map. 然后遍历所有的点,找出 对角的两个点, 再去map里确认是否存在剩下的两个对角点,计算面积,一直保留最小的那个面积. Java Solution: Runtime: 214 ms, faster than 78.80% Memory Usage: 61.5 MB, less than…
