55. Jump Game 第一种方法: 只要找到一个方式可以到达,那当前位置就是可以到达的,所以可以break class Solution { public: bool canJump(vector<int>& nums) { int length = nums.size(); ) return false; vector<bool> dp(length,false); dp[] = true; ;i < length;i++){ ;j >= ;j--){…

45. 跳跃游戏 II 动态规划 此题可以倒着想. 看示例: [2,3,1,1,4] 我们从后往前推,对于第4个数1,跳一次 对于第3个数1,显然只能跳到第4个数上,那么从第3个数开始跳到最后需要两次 对于第2个数3,显然一步到位,跳一次 对于第一个数2,只能选择跳一次还是跳两次,显然选择跳一次的收益更大,最终只需跳两次 倒着推时发现满足①最优子结构,②重叠子问题.可以使用动态规划. 状态描述:f[i]表示在第i个位置最小需要几次可跳到最后一个位置 状态转移方程:f[i] = min(f[i+1…
