Help me please! What's wrong with my program??

#include <iostream>
using namespace std;

#define ll unsigned long long

ll f(ll* a)
{
swap(a[4], a[5]);

for (int i=1; i<=3; i++)
if (a[2*i-1]>a[2*i])
swap(a[2*i-1], a[2*i]);

for (int c=1; c<=3; c++)
for (int i=1; i<3; i++)
if (a[2*i-1]>a[2*i+1])
{
swap(a[2*i-1], a[2*i+1]);
swap(a[2*i], a[2*i+2]);
}

return a[6]+10*a[5]+100*a[4]+1000*a[3]+10000*a[2]+100000*a[1];
}

ll a[100001][7], sol[800][100010], sum;

int main()
{
ll n, k=0, sum;
cin>>n;

for (ll i=1; i<=n; i++)
{
for (int j=1; j<=6; j++)
cin>>a[i][j];

sum=f(a[i]);
//cout<<"i="<<i<<" "<<sum<<endl;

bool f=true;
for (ll cnt=1; cnt<=k; cnt++)
if (sol[cnt][100009]==sum)
{
f=false;
ll tmp=++sol[cnt][0];
sol[cnt][tmp]=i;
break;
}

if (f)
{
++k;
sol[k][0]=1;
sol[k][1]=i;
sol[k][100009]=sum;
}
}

cout<<k<<endl;
for (ll i=1; i<=k; i++)
{
for (ll j=1; j<=sol[i][0]; j++)
cout<<sol[i][j]<<" ";
cout<<endl;
}

}
