# The puzzle is Tower of Hanoi…[Cprogm]FTC

Laaslya is planning to go to the cinema theater to spend her weekend vacation. Her friends Tina, Caleb, and Jocelyn all knew about Laasya’s plan. They say we are coming too, but she thinks to ignore them because only Laasya has enough money to pay for the cinema ticket.

Laasya is very good at programming, so she puts up a puzzle to avoid taking her friends to the cinema. She also says that those who have finished this can come with me.

The puzzle is Tower of Hanoi is a mathematical puzzle where we have three rods and n disks. The objective of the puzzle is to move the entire stack to another rod. the number of the disk will be given as input obeying the following simple rules:

1) Only one disk can be moved at a time.

2) Each move consists of taking the upper disk from one of the stacks and placing it on top of another stack i.e. a disk can only be moved if it is the uppermost disk on a stack.

3) No disk may be placed on top of a smaller disk.

``````Input:
The input represents the single line integer “n”

Output:
Display the Movement of the disk.``````
```#include <stdio.h>
void tHanoi(int n,char from_rod,char to_rod,char aux_rod)
{
if(n==1)
{printf("Move disk 1 from rod %c to rod %c\n",from_rod,to_rod);
return;
}
tHanoi(n-1,from_rod,aux_rod,to_rod);
printf("Move disk %d from rod %c to rod %c\n",n,from_rod,to_rod);
tHanoi(n-1,aux_rod,to_rod,from_rod);
}
int main()
{
int num;
scanf("%d",&num);
tHanoi(num,'A','C','B');
return 0;
}```
