题意: 给出n项的数列A[ ], q个询问, 询问 [ l, r ] 之间项的和. 求A的全排列中该和的最大值. 思路: 记录所有询问, 利用差分数列qd[ ], 标记第 i 项被询问的次数( 每次区间增1 ). 最后对qd, A 进行升序排序, 对应项相乘, 求和. 理由是: 越大的数被询问覆盖的次数越多那么总和就越大. 差分数列简单易用. #include <cstdio> #include <cstring> #include <algorithm> using…

CF 628C 题目大意:给定一个长度为n(n < 10^5)的只含小写字母的字符串,以及一个数d,定义字符的dis--dis(ch1, ch2)为两个字符之差, 两个串的dis为各个位置上字符的dis之和,求和给定的字符串的dis为d的字符串,若含有多个则输出任意一个,不存在输出-1 解题思路:简单贪心,按顺序往后,对每一个字符,将其变为与它dis最大的字符(a或者z),d再减去相应的dis, 一直减到d为0,剩余的字母则不变直接输出.若一直到最后一位d仍然大于0,则说明不存在,输出-1. /…
