  • 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.

    • To solve this problem, we can use the Floyd's Cycle-Finding Algorithm.

    • 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 ...

  • Ans. 

    The minimum depth of a binary tree is the number of nodes along the shortest path from the root node down to the nearest leaf node.

    • The minimum depth can be found by performing a breadth-first search (BFS) traversal of the binary tree

    • During the BFS traversal, keep track of the current level and increment the depth by 1 for each level

    • Stop the BFS traversal when a leaf node is encountered and return the depth as the minim

    • Compare the elements at the current pointers and move the pointers accordingly.

    • If the elements are equal, add it to the intersection array and move both pointers.

    • If the element in the first array is smaller, move the first 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.
