Check If It Is a Straight Line
You are given an integer array coordinates, where coordinates[i] = [x, y] represents the coordinate of a point. Check if these points make a straight line in the XY plane.
Return true if all the points lie on a single straight line, and false otherwise.
Example 1
Input
coordinates = [[1,2],[2,3],[3,4],[4,5],[5,6],[6,7]]Output
trueAll the points lie on the same straight line.
Example 2
Input
coordinates = [[1,1],[2,2],[3,4],[4,5],[5,6],[7,7]]Output
falseThe point [3, 4] does not lie on the same straight line as the others.
Constraints
- 2 <= coordinates.length <= 1000
- coordinates[i].length == 2
- -10^4 <= coordinates[i][0], coordinates[i][1] <= 10^4
- coordinates contains no duplicate point.
