3.推断到这个点后往后跳的步数是不是大于max,假设是就更新max,不是就继续往前走 这种话我们能够看到:假设前面这个点是零,且这个时候step步数不够你迈过去,那么就会自己主动跳出返回false。 可是假设能够一直这么走走到终点,那么返回true package testAndfun; public class jumpGame { public static void main(String...
确定你是否能够到达最后一个索引。 Example 1: Input: [2,3,1,1,4] Output: true Explanation: 第一步,跳2步到索引2,第二步跳1步到索引3,第三步跳1 步到索引4,到达 步到索引3,第三步跳1步到索引4,到达 步到索引2,第二步跳1步到索引3,第三步跳1步到索引4,到达 第一步,跳1步到索引1,第二...
LeetCode 1340. Jump Game V (Java版; Hard) 题目描述 Given an array of integers arr and an integer d. In one step you can jump from index i to index: i + x where: i + x < arr.length and 0 < x <= d. i - x where: i - x >= 0 and 0 < x <= d. In addition, you ...
时间O(N) 空间 O(1) 思路 如果只是判断能否跳到终点,我们只要在遍历数组的过程中,更新每个点能跳到最远的范围就行了,如果最后这个范围大于等于终点,就是可以跳到。 代码 public class Solution { public boolean canJump(int[] nums) { int max = 0, i = 0; for(i = 0; i <= max && i < nums...
