http://uoj.ac/problem/13 建立trie树,然后建立go指针, 和AC自动机里的fail指针差不多, 走到一个快捷方式就从go指针走. 注意在trie树上要保留字符'/',不能用end标记来标识一个字符串的结束. 因为可能出现"/Iam/zz"和"/Iamzz"这两种情况,如果只用end标记,tire树上这两个字符串就会共用一条路径. (总之是蒟蒻才会犯的错误,神犇们勿喷_(:з」∠)_) #include<cstdio> #inc…

关于 caesum.com 网上上的题目,分类有Sokoban,Ciphers,Maths,Executables,Programming,Steganography,Misc.题目有点难度,在努力奋战中…… problem 21 Factor 数806515533049393最大的质因数是多少? 因数分解题,32位int范围在四十亿左右.我是这么记这个大概值的,全球六十多亿人口,很多人还不能上网,而且有局域网的存在,IP本来够用的,因为北美划用了很多,导致了现在的IP不够用,出现了IPv6.6…

题目链接:http://codeforces.com/problemset/problem/13/E 题意:给定n个弹簧和每个弹簧初始的弹力a[].当球落在第i个位置.则球会被弹到i+a[i]的位置. 现在有2种操作: 1 a b:把第a个弹簧的弹力修改为b. 2 a:当球初始放入的位置为a时,需要弹几次才会弹出n.弹出前的最后一个位置是多少. 输出位置和次数. 思路:和BZOJ 2002一样. 然后记录一个最后弹出去的位置preidx.每次弹出当前块的时候记录当前的位置即可.然后最后再暴力模拟…
