Has to ask multiple times to receive response. Seems engineering department isn't capable enough to decide what they actually want from candidate and what should be the outcome of questions asked.

  • Ans. 

    The task is to determine if a given singly linked list forms a cycle or not.

    • A cycle occurs when a node's next points back to a previous node in the list.

    • The algorithm uses two pointers, one moving at a normal pace and the other moving twice as fast.

    • If there is a cycle, the fast pointer will eventually catch up to the slow pointer.

    • If the fast pointer ...

  • Q3. What is the difference between a mutex and a semaphore?
  • Ans. 

    A mutex is a binary semaphore used for mutual exclusion, while a semaphore is a generalized synchronization primitive.

    • Mutex is used to protect a critical section of code, allowing only one thread to access it at a time.

    • Semaphore is used to control access to a shared resource, allowing multiple threads to access it simultaneously.

    • Mutex has ownership, meaning the thread that locks it must unlock it.
