Q.no.1: Write a program to perform the function of tower of hanoi…

A.no.1:

import java.io.*;
class tower
{
public void transfer(int n,char from,char to,char temp)
{
if(n>0)
{
transfer(n-1,from,temp,to);
System.out.println("Move disc "+n+" from "+from+" "+"to "+to);
transfer(n-1,temp,to,from);
}
return;
}
public static void main(String args[])throws IOException
{
tower ob=new tower();
int n;
InputStreamReader inp=new InputStreamReader(System.in);
BufferedReader buff=new BufferedReader(inp);
System.out.println("How many discs...???");
n=Integer.parseInt(buff.readLine());
ob.transfer(n,'A','B','C');
}
}
Output:

How many discs...???
3
Move disc 1 from A to B
Move disc 2 from A to C
Move disc 1 from B to C
Move disc 3 from A to B
Move disc 1 from C to A
Move disc 2 from C to B
Move disc 1 from A to B

Algorithm:

Operation— Tower of Hanoi.
Input— Number of discs.
Output— Position of discs.

Steps—

1): define the class name “tower”.
2): start a function “transfer”, with

Q.no.2. Write a program to accept a word or a sentence and display it in PIGLATIN form.

}
public void latin()throws IOException
{
