Interview Questionnaire 

11 Questions

  • Q1. Detecting loop in linked list
  • Ans. 

    Detecting loop in a linked list

    • Use two pointers, one moving one node at a time and the other moving two nodes at a time

    • If there is a loop, the two pointers will eventually meet

    • If any of the pointers reach the end of the list, there is no loop

  • Answered by AI
  • Q2. Write code for dfs
  • Ans. 

    DFS (Depth-First Search) is a graph traversal algorithm that explores as far as possible along each branch before backtracking.

    • DFS uses a stack to keep track of visited nodes and explore adjacent nodes.

    • It can be implemented recursively or iteratively.

    • DFS is useful for solving problems like finding connected components, detecting cycles, and solving mazes.

  • Answered by AI
  • Q3. How to find cycle in graph
  • Ans. 

    To find a cycle in a graph, use depth-first search (DFS) and keep track of visited nodes.

    • Implement DFS algorithm to traverse the graph

    • Maintain a visited array to keep track of visited nodes

    • If a visited node is encountered again during DFS, a cycle exists

  • Answered by AI
  • Q4. What is hashing and how will you implement?
  • Ans. 

    Hashing is a process of converting data into a fixed-size numerical value called a hash code.

    • Hashing is used to quickly retrieve data from large datasets.

    • It is commonly used in data structures like hash tables and hash maps.

    • Hash functions should be fast, deterministic, and produce unique hash codes for different inputs.

    • Examples of hash functions include MD5, SHA-1, and SHA-256.

  • Answered by AI
  • Q5. Questions related to to resume
  • Q6. No of pairs between 1 and N satisfy relation pow(a,3)+pow(b,3)=pow(c,3)+pow(d,3).a,b,c,d<=N
  • Ans. 

    The question asks for the number of pairs between 1 and N that satisfy a specific mathematical relation.

    • The relation is pow(a,3) + pow(b,3) = pow(c,3) + pow(d,3)

    • The values of a, b, c, and d should be less than or equal to N

    • Count the number of pairs that satisfy the relation

  • Answered by AI
  • Q7. -----.php?pid=514
  • Q8. Questions related to resume
  • Q9. Explain Merge sort
  • Ans. 

    Merge sort is a divide-and-conquer algorithm that recursively divides an array into two halves, sorts them, and then merges them.

    • Divide the array into two halves

    • Recursively sort each half

    • Merge the sorted halves back together

    • Repeat until the entire array is sorted
