One day twoseven ask me also for solution during a contest. i said no i will not cheat. he used bad words. He is buying solution with money. He got admission in LPU also with money. His parent should be ashamed for him. People like this spoiling the reputation of India. he is Desh drohi. He is shame to India.

One day sure codeforces rating will become like codechef rating because of people like him. Candidate Master will be joke. people doing working hard for candidate master there hard work will be wasted. He is spoiling and dilutioning codeforces. He should be banned for sake of codeforces.

he is karangreat verson 2.0

bool done = false;

void go(ll a, ll b, ll c)
{
    ll tm = ((why * (b - a)) % mod + mod) % mod;
    ll chk = tm * 708;
    if((b - c + chk) % mod == 0)
    {
        ll nano = tm % (ll)1e9;
        tm /= 1e9;
        ll sec = tm % 60;
        tm /= 60;
        ll min = tm % 60;
        ll hr = tm / 60;
        cout<<hr<<" "<<min<<" "<<sec<<" "<<nano<<endl;
        done = true;
    }
}
