Posted by Erik Arakelyan(AUA) 3 Apr 2015 14:50
#include <iostream>
using namespace std;
bool Chekcker(int A[],int k)
{
int i,j,v;
bool circle=true;
for(j=1;j<=k;j++)
for(v=1;v<=k;v++)
{
if(A[v]==0 && A[j]==v )
A[j]=0;
}

for(j=1;j<=k;j++)
for(v=1;v<=k;v++)
{
if(A[j]==0 && A[v]==j )
A[v]=0;
}
for(v=1;v<=k;v++)
if(A[v]==0)
{ circle=true;}
else{circle=false;break;}

return circle;
}

int main() {
int n;
cin>>n;
int i,j,k = 0,v;
int temK;
bool circle;
int conf;
int A[30000];
for(i=1;i<=n;i++)
{
cin>>k;
j=1;
v=1;
temK=k;
circle=true;
conf=0;

for(j=1;j<=k;j++)
{
cin>>A[j];

}

for(j=1;j<=k;j++)
{
if(A[j]==0)
conf++;
}

circle=Chekcker(A,k);

if(conf==0 || conf>1)
{circle=false;}

if(circle==true)
cout<<"YES"<<endl;
else
cout<<"NO"<<endl;

for(v=1;v<=k;v++)
A[v]=0;

}

return 0;
}

this code get correct on every test in the forum, however fails test #3. Whats Wrong????
