Break The Cycle (Floyd's Cycle)

Hi sir,
I tried to implement a function to break the cycle. Can you please check it out and correct me as well as give me the feedback?

Thanks a lot.

You code is correct.
You can avoid the last loop traversal in line 14-15 if you maintain a previous node pointer for the fast pointer in 2nd loop traversal.
Anyways, your solution is correct.
