1 #include<bits/stdc++.h> 2 using namespace std; 3 typedef long long ll; 4 int main() { 5 int n; 6 cin>>n; 7 if(n==0){ 8 cout<<"1 1"<<'\n'; 9 cout<<"1"<<'\n';; 10 } 11 else{ 12 int tmp=1; 13 while(tmp<=n) 14 tmp<<=1; 15 cout<<"2 3"<<'\n'; 16 cout<<tmp+n<<" "<<n<<" "<<0<<'\n'; 17 cout<<tmp<<" "<<tmp+n<<" "<<n<<'\n'; 18 } 19 return 0; 20 }
