为迎接9月14号hdu命题的长春网络赛 ACM弱校的弱菜,苦逼的在机房(感谢有你)呻吟几声: 1.对于本次网络赛,本校一共6名正式队员,训练靠的是完全的自主学习意识 2.对于网络赛的群殴模式,想竞争现场赛名额,只有泪奔%>_<% 3.至于带队教练的请师兄帮帮忙,如果可以的活,他们能在训练过程中指导,岂不更好,个人对此表示不乐观 虽然形式很不乐观,但我们还是努力着,尽人事,然后…… 至于最终结果拭目以待吧 o(╯□╰)o 杭电上的题目 4267 A Simple Problem with Int…

今天(2013/9/28)长春站,最后一场网络赛! 3~5分钟后有队伍率先发现伪装了的签到题(博弈) 思路: 与取石头的巴什博弈对比 题目要求第一个人取数字在[1,k]间的某数x,后手取x加[1,k]内的某数. 将输入的n看做n个石头并编号,后一次取得的是[1,k]中的石头编号. #include<stdio.h> int main() { int n,k; while(scanf("%d%d",&n,&k)!=EOF) { &&k==)br…

题目链接:http://acm.hdu.edu.cn/showproblem.php?pid=4764 题意:Tang 和 Jiang 玩一个游戏,轮流写下一个数,Tang先手,第一次Tang只能写[1,k]之间的数,X表示上一个人写的数,Y表示下一个人写的数,每次必须满足 1<=Y-X<=k,直到有一个人写下的数不小于n,写下那个数的人失败,游戏结束,输出胜利的人. 分析:可以看做是取石子游戏,有一堆n-1个的石子,两个人轮流去石子,每次最多能去k个,如果没有石子可取则输,这就将问题转化为巴…

一个组合游戏题. 解答: 从后面往前面推,首先n-1是必胜位,然后前面的k位是必败位,如此循环下去.所以题目就容易了! 代码: #include<cstdio> using namespace std; int main() { int n,k; while(scanf("%d%d",&n,&k)&&(n+k)) { ); )puts("Tang"); else puts("Jiang"); } ; }…

这次的答案是猜出来的,如果做得话应该是应该是一个几何概型的数学题: 答案就是:n/(m^(n-1)); 具体的证明过程: 1.首先枚举这M个点中的的两个端点,概率是:n*(n-1); 2.假设这个蛋糕是个圆盘状的,圆面面积为1,然后为了满足题目的要求,这两个端点+圆心所组成的扇形的的面积应该小于1/m: 3.然后对剩下的所有点都应该分布在这个扇形里面,加设扇形面积为x,则结果应该为:x^(n-2)在0-1/m中的积分,然后再乘以n*n-1; n,m<=20.这牵扯到大数运算,为了简单起见就用了J…

一个KMP的简单题 不过好久没用过这个东东了,今天写的时候花了很多时间: 只需要花点时间判断下所有的元素都相同的的情况就行了! #include<cstdio> #include<cstring> #include<algorithm> #define maxn 1000006 using namespace std; char s[maxn]; int next[maxn]; void getnext(char *t) { // t为模式串 ,j= -,l = str…
