DIY: K Closest Points to Origin
Solve the interview question "K Closest Points to Origin" yourself in this lesson.
We'll cover the following
Problem statement
We have an array of points on the plane. Find the K
closest points to the origin (0, 0)
.
Note: Here, the distance between two points on a plane is the Euclidean distance.
Input
The input will be an array of points and a value k. The following is an example input:
points = [[1,3],[-2,2]]
k = 1
Output
The output will be the k points from the points
array that are closest to the origin. For the above input, the output will be:
[-2,2]
Coding exercise
For this coding exercise, you need to implement the function kClosest(points, k)
, where points
is the array of multiple pairs of points in the form [x,y]
and k
represents the number of closest points that you have to find. The function will return the k
points that are closest to the origin.
