AC code根本不需要理会“http://"的问题哦
后来删除了那个多余的东西终于过了
code:
#include <iostream.h>
#include <string.h>
int i,j,l;
int i0,k,temp;
int b[1001];
int f[1001];
char a[1001][100];
void p(int x)
{
cout<<a[x]<<endl;
}
void init()
{ i=0;j=0;k=1;
char a0[]="http://www.acm.org/";
for(l=0;a0[l];l++){
a[1][l]=a0[l];
}
temp=1;
}
void visit()
{
b[++i]=temp;
cin>>a[++k];
temp=k;
p(temp);
j=0;
}
void back()
{
if(i>0){
f[++j]=temp;
temp=b[i];
--i;
p(temp);
}
else{cout<<"Ignored"<<endl;}
}
void forward()
{
if(j>0){
b[++i]=temp;
temp=f[j];
--j;
p(temp);
}
else{cout<<"Ignored"<<endl;
}
}
int main()
{
init();
while(1)
{
char c[100];
cin>>c;
if(c[0]=='V'){visit();}
else if(c[0]=='B'){back();}
else if(c[0]=='F'){forward();}
else if(c[0]=='Q'){break;}
}
return 0;
}
