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.
Example 1:
Input: coordinates = [[1,2],[2,3],[3,4],[4,5],[5,6],[6,7]]
Output: true
Example 2:
Input: coordinates = [[1,1],[2,2],[3,4],[4,5],[5,6],[7,7]]
Output: false
Constraints:
2 <= coordinates.length <= 1000 coordinates[i].length == 2 -10^4 <= coordinates[i][0], coordinates[i][1] <= 10^4 coordinates contains no duplicate point.
