 思路参考：力扣https://leetcode-cn.com/problems/jump-game/solution/pythonji-bai-97kan-bu-dong-ni-chui-wo-by-mo-lan-4/

代码：

class Solution:
    def canJump(self, nums: List[int]) -> bool:
        max_dis = 0

        for inx, value in enumerate(nums):
            if max_dis >= inx and inx + value >= max_dis:
                max_dis = max(max_dis, inx + value)

        return max_dis >= inx
