5 b) Solving Tower of Hanoi problem with n disks.
PROGRAM:
#include <stdio.h>
void tower(int n, int source, int temp, int destination)
{
if (n == 0)
return;
tower(n - 1, source, destination, temp);
printf("\nMove disc %d from %c to %c", n, source, destination);
tower(n - 1, temp, source, destination);
}
void main()
{
int n;
printf("\nEnter the number of discs: \n");
scanf("%d", & n);
tower(n, 'A', 'B', 'C');
printf("\n\nTotal Number of moves are: %d", (int) pow(2, n) - 1);
}
OUTPUT:
Enter the number of discs: 3
Move disc 1 from A to C
Move disc 2 from A to B
Move disc 1 from C to B
Move disc 3 from A to C
Move disc 1 from B to A
Move disc 2 from B to C
Move disc 1 from A to C
Total Number of moves are: 7
