my code is https://ide.codingblocks.com/s/111864
test case 2 is showing run error please tell the reason.
In the question Circular linked list the SAMPLE INPUT is
1 2 3 4 5 2 3 -1 so the circular list the cycle is not repeating from 1 its repeatig from 2 . so how to solve this problem
Testcase 2 run error

I have correct the null pointer exception,As ref was pointing to null just added ref!=null in the while condition.
I hope you understands your approach is wrong,it will give correct answer only when the cycle starts from the beginning of the loop.
Consider 1 2 3 4 5 2 3 -1 the loop starts from 2,how will your code tackle this out.
For this we need to know standard Algorithm Flyodd Warshall loop detection Algorithm.
I hope I’ve cleared your doubt. I ask you to please rate your experience here
