LeetCode K Closest Points to Origin 132131
We have a list ofpointson the plane. Find theKclosest 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 unique (except for the order that it is in.) E...
