    1232 - Check If It Is a Straight Line.

    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.

    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.
