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…

题目如下: Given a set of points in the xy-plane, determine the minimum area of a rectangle formed from these points, with sides parallel to the x and y axes. If there isn't any rectangle, return 0. Example 1: Input: [[1,1],[1,3],[3,1],[3,3],[2,2]] Output…
