I applied via Naukri.com and was interviewed before Nov 2023. There were 4 interview rounds.

Round 1 - One-on-one 

(2 Questions)

  • Q1. Detect and remove loop in a single linked list
  • Ans. 

    To detect and remove a loop in a single linked list, we can use Floyd's Cycle Detection Algorithm.

    • Use two pointers, slow and fast, to detect a loop in the linked list.

    • Move slow pointer by one step and fast pointer by two steps. If they meet at some point, there is a loop.

    • To remove the loop, find the start of the loop using Floyd's Algorithm and then remove the loop by breaking the link.

  • Answered by AI
  • Q2. Clone a linked list with random and next pointer
  • Ans. 

    Cloning a linked list with random and next pointers involves creating a deep copy of the original list while maintaining the connections between nodes.

    • Create a mapping of original nodes to their corresponding new nodes

    • Iterate through the original list and create new nodes with the same values

    • Update the random and next pointers of the new nodes based on the mapping created
