We have a list of points on the plane. Find the K closest points to the origin (0, 0). (Here, the distance between two points on a plane is the Euclidean distance.) You may return the answer in any order. The answer is guaranteed to be...
(Here, the distance between two points on a plane is the Euclidean distance.) You may return the answer in any order. The answer is guaranteed to be unique (except for the order that it is in.) Example 1: Input: points =[[1,3],[-2,2]], K =1 ...
Input: points = [[3,3],[5,-1],[-2,4]], K = 2Output: [[3,3],[-2,4]] (The answer [[-2,4],[3,3]] would also be accepted.) 题意 求离原点距离最近的K个点 思路 维护一个minHeap 代码 1classSolution {2publicint[][] kClosest(int[][] points,intK) {3int[][] res =...
