cin>>n;
cal(n,'A','B','C');
cout<<"\n/*\nName-Sanjampreet Singh\nRoll Number-1507967\n*/";
}
void cal(int n,char source,char inter,char dest)
{
if(n==1)
cout<<"Disk 1 from "<<source<<" to "<<dest<<endl;
else
{
cal(n-1,source,dest,inter);
cout<<"Disk "<<n<<" from "<<source<<" to "<<dest<<endl;
cal(n-1,source,dest,inter);
