Problem description

Description You are given an integer array coordinates, coordinates[i] = [x, y], where [x, y] represents the coordinate of a point. Your task is to check if these points make a straight line in the XY plane.

Examples

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

Constraints

2 <= coordinates.length <= 1000 coordinates[i].length == 2 -10^4 <= coordinates[i][0], coordinates[i][1] <= 10^4 coordinates contains no duplicate point.
