Ans. 
This was an output-based question asked in the C Programming section.
This was an easy question but tricky as well. If you are not clear with C basics.

Ans. 
It is realized that Floyd's Cycle recognition calculation ends when quick and slow pointers meet at a typical point. This normal point is otherwise called one of the loop nodes. Store the location of this normal point in a pointer variable, say (ptr). Then, at that point, introduce a counter with 1 and begin from the common point, and continues to visit the following node and increase the counter till the common pointe...read more
