if(n>=1){
TOH(n-1,beg,end,aux);
System.out.println("Moving ring "+ n + " from “+beg+” to "+end);
TOH(n-1,aux,beg,end);
}}
public static void main(String args[]){try{
Scanner sc=new Scanner(System.in);

#2

import java.util.*;
public class Main {

public static void TOH(int n,char beg ,char aux ,char end){
	if(n>=1){
	TOH(n-1,beg,end,aux);
	System.out.println("Moving ring "+ n + " from "+beg+" to "+end);  // MISTAKE: use " " for the string
	TOH(n-1,aux,beg,end);
	}}
	public static void main(String args[]){
	Scanner sc=new Scanner(System.in);
	int n=sc.nextInt();
	TOH(n,'A','C','B');    //mistake: see the qn B-destination rod and C rod is helper rod

	}

}
