把dfs改成
```
int dfs(int u,int flow)
{
if(u==T)
return flow;
int temp=flow;
for(int &i=cur[u];i;i=e[i].nxt)
if(dep[e[i].v]==dep[u]+1&&e[i].w!=0){
int di=dfs(e[i].v,min(flow,e[i].w));
if(!di) dep[e[i].v]=0;
e[i].w-=di;
e[i^1].w+=di;
temp-=di;
}
return flow-temp;
}
```
之后你的wrong output format Unexpected end of file - int32 expected 问题可以得到解决但仍然是11分，
可能是细节问题

@[沐忆](/space/show?uid=62090) 把整个程序改成
```
#include<bits/stdc++.h>

void deal(int num);
int Dinic();
bool bfs();
int dfs(int u,int flow=Inf);
void add_edge(int u,int v,int w,bool flag=true);
int main()
{
scanf("%d%d",&n,&m);

}
int Dinic()
{

}
bool bfs()

}
}
return 0;
}
void add_edge(int u,int v,int w,bool flag)
{
cnt++;
e[cnt].v=v;
e[cnt].w=w;
e[cnt].nxt=head[u];
head[u]=cnt;
if(flag) add_edge(v,u,0,false);
}
void deal(int num)
{
memset(tools,0,sizeof(tools));
cin.getline(tools,10000);
int ulen=0,tool;
while(sscanf(tools+ulen,"%d",&tool)==1){
add_edge(num,tool+n,Inf);
if(tool==0) ulen++;
else{
while(tool){

ulen++;
}
}
}
}
```
就可以了

ps：你的wrong output format Unexpected end of file - int32 expected错误的确是printf导致的
