http://poj.org/problem?id=1426 Description Given a positive integer n, write a program to find out a nonzero multiple m of n whose decimal representation contains only the digits 0 and 1. You may assume that n is not greater than 200 and there is a c…

没什么巧办法,直接搜就行. 用余数作为每个节点的哈希值. #include <cstdio> #include <cstring> #include <cstdlib> ; struct node { int mod; int fa; int digit; node() {} node( int mod, int fa, int dig ):mod(mod), fa(fa), digit(dig) { } }; int N; ]; bool vis[MAXN]; nod…

题意:求m的倍数中不包含一些数码的最小倍数数码是多少.比如15 ,不包含0  1 3,答案是45. BFS过程:用b[]记录可用的数码.设一棵树,树根为-1.树根的孩子是所有可用的数码,孩子的孩子也是所有可用的数码.这样从根到叶子节点这条路径所组成的数表示一个可行的数. __                 __ 剪枝:(A % m ==  B % m)  =>  (AX % m ==  BX % m)   即如果搜索到一个数X, X%m == a (a !=0) , 则以后如果搜索到Y , Y…
