Interview Preparation Tips

Interview preparation tips for other job seekers - First Technical Round was relatively easy but Second Technical round was definitively hard. The interviewer emphasized more on the know-how of the techniques to solve the problem, focusing on when and why to apply an algorithm and where not to apply the algorithm. He also emphasized whether the candidates understand the data before applying the algorithms. So prepare extremely well with solid hands on experience before going for Angel One interview.

Maintain two pointers, one moving at double the speed of the other, if they meet at any point, there is a cycle.
If one of the pointers reaches the end of the list (null), there is no cycle.
