Solution Review: Recursive Towers of Hanoi

Explore the recursive approach to solving the Towers of Hanoi problem using C programming. Understand how the move function handles disk transfers between pegs with base and recursive cases, and learn how the algorithm adapts for different numbers of disks. This lesson guides you through recursive problem-solving and function call sequences.

We'll cover the following...

Solution

See the code given below!

C
#include <stdio.h>

void move ( int, char, char, char ) ;



int main( )

{

	int n = 3 ;

	move ( n, 'A', 'B', 'C' ) ;

	return 0 ;

}



void move ( int n, char sp, char ap, char ep )

{

	if ( n == 1 )

		printf ( "Move from %c to %c\n", sp, ep ) ; 

	else

	{

		move ( n - 1, sp, ep, ap ) ; 

		move ( 1, sp,' ', ep ) ; 

		move ( n - 1, ap, sp, ep ) ;

	}

}

Explanation

The code given above shows the prototype of the move( ) and the first call to ...
