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. /…

系统架构是B/S,开发语言是C#.silverlight,开发平台是.NET,数据库为sqlserver,这是我读研究生时候自己做的作品,以自己的母校为地图,进行GIS相关的功能分析,核心的模块有:空间查询.GPS定位模拟.搜索模块.统计分析:其中说的不足之处,望各位指点出来. 一.空间查询      整体思路:空间查询是用户在地图上框选一定范围,然后根据框选范围Geometry来进行query查询.框选利用Draw工具有多边形.矩形.圆线等方式.实现方式,前台界面设计: <!--Toolbar…
