渐渐认识到区域赛更侧重的是思维及基本算法的灵活运用,而不是算法的量(仅个人见解),接下来要更多侧重思维训练了. 区间DP,dp[i][j]表示从i到j最终剩余第i 与第j只的最小伤害值,设置0与n+1两个虚拟的狼,状态转移方程如下: dp[i][j] = min(dp[i][j], dp[i][k] + dp[k][j] + b[i] + b[j]) #include<cstdio> #include<iostream> #include<cstdlib> #inclu…

题意 就是有一对狼,每个狼有初始的攻击力,并且还能给左右两边的狼提供攻击力加成,当冒险家杀死一头狼的时候他也会受到这个狼目前攻击力的伤害 实例解析 33 5 78 2 0 有三头狼,刚开始第二头狼给他左右两边的狼各加2攻击力,由于第一头狼左边没有狼,所以只给第二头狼加,第三头狼还那样,一系列操作后攻击力为(5,13,9),从左往右杀死狼 1.受到5点攻击,且第二头狼的攻击力加成消失(5,9) 2.受到5点攻击,且第三头狼攻击加成消失(7) 3最后结果5+5+7=17 题解 dp[i][j]=mi…
