WA,匹配怎么做的啊?大牛们~#include <iostream> using namespace std; const int N=111; int n,f,d,Fcnt[N],Dcnt[N],F[N],D[N],link[N]; bool s[N],g[N][N],v[N][N][N],use[N],canuse[N]; bool find(int a) { int i,j; for(i=1;i<=d;i++) { if(!s[i]&&g[a][i]) { for(j=1;j<=n;j++) { if(v[a][i][j]&&canuse[j]) { canuse[j]=false; s[i]=true; if(link[i]==0||find(link[i])) { link[i]=a; return true; } } } } } return false; } int main() { int i,j,k; scanf("%d%d%d",&n,&f,&d); for(i=1;i<=n;i++) { scanf("%d%d",&Fcnt[i],&Dcnt[i]); for(j=1;j<=Fcnt[i];j++) scanf("%d",&F[j]); for(j=1;j<=Dcnt[i];j++) scanf("%d",&D[j]); for(j=1;j<=Fcnt[i];j++) for(k=1;k<=Dcnt[i];k++) {g[F[j]][D[k]]=true;v[F[j]][D[k]][i]=true;} } int ans=0; for(i=1;i<=f;i++) { memset(s,false,sizeof(s)); memset(canuse,true,sizeof(canuse)); if(find(i))ans++; } printf("%d\n",ans); return 1; } Followed by:
