这道题目是队友写的,貌似是用暴力枚举出来. 题意:给出一组数,要求这组数在解锁的界面可能的滑动序列. 思路:按照是否能够直接到达建图,如1可以直接到2,但是1不能直接到3,因为中间必须经过一个2. 要注意的假如2已结访问过,那么1就可以直接到2. 建图DFS,图要更新. Source Code: #include <stdio.h> #include <string.h> ], ans[], n, vis[], k, fun[][]; ][] = { {}, {,,,,,,,,,}…
http://acm.zju.edu.cn/onlinejudge/showProblem.do?problemCode=3861 这道题当时没做出来,后来经过队友提醒才做出来. 3*3的九宫格,给你其中n个点按下面要求连起来: 1. 给你的n个点都要激活(至少经过一次) 2. 如果点A,B相连后要经过另一个点C,则C在序列中的位置必须在A,B之前 如 1 7 4是不合法的 3.线段相交是没关系的,如 7 6 9 4 我是直接生成n个数的全排列,然后在所有排列里面去掉不合法的. #include…

在Log4Qt中存在一个比较大的问题,当使用 DailyRollingFileAppender对日志进行输出时,会无限输出文件,也就是说,当系统运行很久时,日志文件有可能很大,大到无法想象.因此,很多开发者希望在DailyRollingFileAppender中加一个属性,用于配置日志文件的个数. 但是如何做呢? 在Java语言中,我找到一个实例,但是在QT中,没能找到,因此,只能通过自己看源代码,分析从而进行改进. 主要代码如下: dailyrollingfileappender.h: cla…
