https://leetcode-cn.com/problems/jump-game-iv/solution/ 给你一个整数数组 arr ,你一开始在数组的第一个元素处(下标为 0)。 每一步,你可以从下标 i 跳到下标: i + 1 满足:i + 1 < arr.length i - 1 满足:i - 1 >= 0 j 满足:arr[i] == arr[j] 且 i != j 请你返回到达数组最后...
输入:nums = [2,3,1,1,4] 输出:true 解释:可以先跳 1 步,从下标 0 到达下标 1, 然后再从下标 1 跳 3 步到达最后一个下标。 示例2: 输入:nums = [3,2,1,0,4] 输出:false 解释:无论怎样,总会到达下标为 3 的位置。但该下标的最大跳跃长度是 0 , 所以永远不可能到达最后一个下标。 提示...
leetcode -- Gas Station -- 跟jump game像,重点--贪心 https://leetcode.com/problems/jump-game/ 思路1:贪心 O(n) 思路就是贪心。子问题就是判断车在第i个position的时候是否可以到达i+1个position,条件就是当前第i个position所加的油gas[i] + diff(就是到达第i个position时剩下来的油,可以看做前面...
