题目一: 一个极其简单的动态规划. class Solution { public: int rob(vector<int>& nums) { ; // 表示没有选择当前houses ; // 表示选择了当前houses ; i < nums.size(); i++){ int temp = best0; best0 = max(best0, best1); // 没有选择当前houses,那么它等于上次选择了或没选择的最大值 best1 = temp + nums[i]; //…

House Robber:不能相邻,求能获得的最大值 House Robber II:不能相邻且第一个和最后一个不能同时取,求能获得的最大值 House Robber III:二叉树下的不能相邻,求能获得的最大值 Paint House:用3种颜色,相邻的房屋不能用同一种颜色,求花费最小 Paint House II:用k种颜色,相邻的房屋不能用同一种颜色,求花费最小Paint Fence:用k种颜色,相邻的可以用同一种颜色,但不能超过连续的2个,求有多少种可能性 198. House Robb…
