Explanation: You will always arrive at index 3 no matter what. Its maximum jump length is 0, which makes it impossible to reach the last index. 方法一:回溯法 1classSolution {2public:3boolcanJump(vector<int>&nums) {4intlen =nums.size();5returncanJump(0, nums, len -1);6}7private:...
Explanation: You will always arrive at index 3 no matter what. Its maximum jump length is 0, which makes it impossible to reach the last index. Constraints: 1 <= nums.length <= 3 * 10^4 0 <= nums[i][j] <= 10^5 这道题和 45. Jump Game 2 很像。思路就是判断是否会停留在一个...
