Maximum Points Inside the Square
You are given a 2D array points and a string s, where points[i] represents the coordinates of point i, and s[i] represents the tag of point i.
A valid square is a square centered at the origin (0, 0), has edges parallel to the axes, and does not contain two points with the same tag.
Return the maximum number of points contained in a valid square.
Note:
- A point is considered to be inside the square if it lies on or within the square's boundaries.
- The side length of the square can be zero.
Example 1
Input
points = [[2,2],[-1,-2],[-4,4],[-3,1],[3,-3]], s = "abdca"Output
2The square of side length 4 covers two points
points[0] and points[1].Example 2
Input
points = [[1,1],[-2,-2],[-2,2]], s = "abb"Output
1The square of side length 2 covers one point, which is
points[0].Constraints
- 1 <= s.length, points.length <= 10^5
- points[i].length == 2
- -10^9 <= points[i][0], points[i][1] <= 10^9
- s.length == points.length
- points consists of distinct coordinates.
- s consists only of lowercase English letters.
