题目连接:Codeforces 442C Artem and Array 题目大意:给出一个数组,每次删除一个数.删除一个数的得分为两边数的最小值,假设左右有一边不存在则算作0分. 问最大得分是多少. 解题思路:首先将连续的a,b,c,a > b && c > b的情况将c掉,获得min(a,b)分,这样处理后数组变成一个递増再递减的序列,除了最大和第二大的取不到.其它数字均能够得分. 例子:4 10 2 2 8 #include <cstdio> #include…

Artem and Array 经过分析我们能发现, 如果对于一个a[ i ] <= a[ i + 1 ] && a[ i ] <= a[ i - 1 ]可以直接删掉. 最后剩下一个先增后减的序列, 除了最大的两个都能加上. #include<bits/stdc++.h> #define LL long long #define fi first #define se second #define mk make_pair #define PLL pair<L…
