Description

有N家洗车店从左往右排成一排,每家店都有一个正整数价格Pi。
有M个人要来花费,第i私有会驶过第Ai个带头一贯到第Bi个洗车店,且会筛选那些店中最平价的五人展览馆开一遍花费。然而只要这些最有扶助的价位高于Ci,那么此人就不洗车了。
请给每家店钦赐多少个价格,使得全体人花的钱的总和最大。

            r_sum -= r_out_sum;
            g_sum -= g_out_sum;
            b_sum -= b_out_sum;
            a_sum -= a_out_sum;

Solution

那道题,脑补了半天愣是……
正解是如此:大家先将ci离散化,设f[l][r][x]表示在[l,r]的洗车店之间的矮小价格为x的最大代价。那么今后枚举三个p,表示小小的价格所在的洗车店为p。那么f[l][r][x]=max(f[l][p−1][x1]+f[p+1][r][x2]+tot)(x1,x2>x)

tot表示左右端点均在[l,r]且凌驾p的人在p为x时的奉献。
我们先来研究什么消逝哪些消除方程中的x1,x2。显著,大家能够修改一下f[l][r][x]的定义,设f[l][r][x]表示在[l,r]的洗车店之间的小小价格至少为x的最大代价。那么式子就形成f[l][r][x]=max(f[l][p−1][x]+f[p+1][r][x]+tot)

我们再来切磋如何计算tot.我们设g[p][x]意味着左右端点均在[l,r]且超越p在p为x时的人的进献。大家得以枚举一下这n个客户,当一个顾客的左右端点均在[l,r]时我们枚举此人资历的点x,并在g[x][c[i]]处+1。最终只要把g[x][j+1]的值加到g[x][j]处即可。
据此最终式子成了f[l][r][x]=max(f[l][p−1][x]+f[p+1][r][x]+g[p][x]∗d[x])

。因为x的枚举是离散化后的,所以未来要用d[x]补回来。
