1266. Minimum Time Visiting All Points
On a plane there are n points with integer coordinates points[i] = [xi,yi]. Your task is to find the minimum time in seconds to visit all points.
*In one second always you can either move vertically, horizontally by one unit or diagonally (it means to move one unit vertically and one unit horizontally in one second).
*You have to visit the points in the same order as they appear in the array.

public int minTimeToVisitAllPoints(int[][] points) {
      int t = 0;
      for(int i = 0;i <points.length-1;i++) {
            t += Math.max(Math.abs(points[i][0]-points[i+1][0]),Math.abs(points[i][1]-points[i+1][1]));
      }
      return t;
}

小结：找到规律，并使用Math的静态方法max、abs；
