Barracuda Networks Interview Questions and Answers

To find a loop in a linked list, we use Floyd's cycle-finding algorithm.

• Floyd's cycle-finding algorithm uses two pointers, one moving at twice the speed of the other.

• If there is a loop in the linked list, the two pointers will eventually meet.

• To detect the meeting point, we reset one of the pointers to the head of the linked list and move both pointers at the same speed.

• The meeting point is the start of the loop.

LRU, MRU and LFU are caching algorithms used to manage memory in computer systems.

• LRU stands for Least Recently Used and removes the least recently used items from the cache when the cache is full.

• MRU stands for Most Recently Used and removes the most recently used items from the cache when the cache is full.

• LFU stands for Least Frequently Used and removes the least frequently used items from the cache when the cache i...read more
