这题就是一个人买还是两个人买,直接选择一下,而且默认是排好了的,就是DP一下,可能不知道DP的人,也是这么写的吧.DP是一种思想啊. #include <bits/stdc++.h> using namespace std; typedef long long LL; typedef unsigned long long ULL; typedef pair<int, int> PI; typedef pair< PI, int> PII; const double ep…

本题大意:排队排票,每个人只能自己单独购买或者和后面的人一起购买,给出k个人单独购买和合买所花费的时间,让你计算出k个人总共花费的时间,然后再稍作处理就可得到答案,具体格式看题意. 本题思路:简单dp,用dp[ i ]来存储前i个人购买票所需要的最小时间,则很容易得出状态转移方程为dp[ i ] = min (dp[i - 1] + a[ i ], dp[i - 2] + b[i - 1]); 参考代码: #include <iostream> #include <cstring>…
