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:
Examples
Example 1
Input: points = [[2,2],[-1,-2],[-4,4],[-3,1],[3,-3]], s = "abdca"
Output: 2
Explanation:
The 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: 1
Explanation:
The square of side length 2 covers one point, which is points[0] .
Example 3
Input: points = [[1,1],[-1,-1],[2,-2]], s = "ccd"
Output: 0
Explanation:
It's impossible to make any valid squares centered at the origin such that it covers only one point among points[0] and points[1] .
Constraints
1 <= s.length, points.length <= 105
points[i].length == 2
-109 <= points[i][0], points[i][1] <= 109
s.length == points.length
points consists of distinct coordinates.
s consists only of lowercase English letters.
