Hints to solve on towers of Hanoi
One of the rule says that "You cannot put a larger disk on top of smaller disk"
So how will you move the n-1 disk to tower B without putting a larger disk on top of a smaller disk assuming you have more than 3 disks
Thank you for your question!
If you have three towers - A, B and C - it is possible to move all the disks from tower A to tower C without putting any large disks on top of smaller disks by using the middle tower B.
You are very welcome to consult a YouTube video and see how this can be done for 4 disks and more :)
