[LeetCode]Jump Game

https://leetcode.com/problems/jump-game/?tab=Description

数组表示青蛙下次能跳的距离，问能否跳到结尾

max记录目前能跳的最远位置，如果当前遍历位置已经跳不到，就永远跳不到结尾了

public class Solution {    public boolean canJump(int[] nums) {        int max = 0;        for (int i = 0; i < nums.length; i++) {            if (i > max) {                return false;            }            max = Math.max(i + nums[i], max);        }        return true;    }}
