Difficulty: Easy
You are given an array coordinates
, coordinates[i] = [x, y]
, where [x, y]
represents
the coordinate of a point. Check if these points make a straight line in the XY plane.
Input: coordinates = [[1,2],[2,3],[3,4],[4,5],[5,6],[6,7]] Output: true
Input: coordinates = [[1,1],[2,2],[3,4],[4,5],[5,6],[7,7]] Output: false
2 <= coordinates.length <= 1000
coordinates[i].length == 2
-10^4 <= coordinates[i][0], coordinates[i][1] <= 10^4
coordinates
contains no duplicate point.
