Solution

class Solution:
    def minTimeToVisitAllPoints(self, points: List[List[int]]) -> int:
        def dist(point1, point2):
            xdist = abs(point1[0] - point2[0])
            ydist = abs(point1[1] - point2[1])
            return max(xdist, ydist)

        n = len(points)

        if n == 1:
            return 0

        ans = 0
        for i in range(n - 1):
            point1 = points[i]
            point2 = points[i + 1]
            ans += dist(point1, point2)
        return ans
