  • Q1. Questions related to the work done at my previous company
  • Q2. Find if a given directed graph is cyclic or not
  • Ans. 

    To check if a directed graph is cyclic or not

    • Use Depth First Search (DFS) algorithm to traverse the graph

    • Maintain a visited set to keep track of visited nodes

    • Maintain a recursion stack to keep track of nodes in the current DFS traversal

    • If a node is visited and is already in the recursion stack, then the graph is cyclic

    • If DFS traversal completes without finding a cycle, then the graph is acyclic

  • Ans. 

    Return a random byte from a stream of bytes with equal probability.

    • Create a variable to store the count of bytes read

    • Create a variable to store the current random byte

    • For each byte read, generate a random number between 0 and the count of bytes read

    • If the random number is 0, store the current byte as the random byte

    • Return the random byte

  • Answered by AI
  • Q4. Find if a given Binary Tree is BST or not
  • Ans. 

    Check if a binary tree is a binary search tree or not.

    • Traverse the tree in-order and check if the values are in ascending order.

    • For each node, check if its value is greater than the maximum value of its left subtree and less than the minimum value of its right subtree.

    • Use recursion to check if all nodes in the tree satisfy the above condition.

  • Answered by AI
  • Q5. Devise an algorithm to determine the Nth-to-Last element in a singly linked list of unknown length. If N = 0, then your algorithm must return the last element. You should parse the list only once
  • Ans. 

    Algorithm to find Nth-to-Last element in a singly linked list of unknown length

    • Traverse the list and maintain two pointers, one at the beginning and one at Nth node from beginning

    • Move both pointers simultaneously until the second pointer reaches the end of the list

    • The first pointer will be pointing to the Nth-to-Last element

    • If N=0, return the last element

    • Parse the list only once

  • Answered by AI
  • Q6. Given an array of integers, print all possible permutations. Also explain your approach
  • Ans. 

    Print all possible permutations of an array of integers

    • Use recursion to swap elements and generate permutations

    • Start with the first element and swap it with each subsequent element

    • Repeat the process for the remaining elements

    • Stop when all elements have been swapped with the first element

    • Print each permutation as it is generated

  • Answered by AI
  • Q7. Design a Stack DS that also prints in O(1) the minimum element you pushed in the stack
  • Ans. 

    Design a stack that prints the minimum element pushed in O(1)

    • Use two stacks, one for storing elements and another for storing minimums

    • When pushing an element, compare it with the top of minimum stack and push the smaller one

    • When popping an element, pop from both stacks

    • To get the minimum element, just return the top of minimum stack

  • Answered by AI
  • Q8. Given a linked list with loop, how would you find the starting point of the loop ?
  • Ans. 

    To find the starting point of a loop in a linked list, use Floyd's cycle-finding algorithm.

    • Use two pointers, one moving at twice the speed of the other.

    • When they meet, move one pointer to the head of the list and keep the other at the meeting point.

    • Move both pointers one step at a time until they meet again, which is the starting point of the loop.

  • Answered by AI
  • Q9. Find a number a matrix mat[m][n] where all the rows and columns are sorted non-decreasingly. What will be the complexity of the solution
  • Ans. 

    To find a number in a matrix where all rows and columns are sorted non-decreasingly. Complexity of the solution.

    • Use binary search to find the number in each row and column

    • Start from the top-right corner or bottom-left corner to optimize search

    • Time complexity: O(m log n) or O(n log m) depending on the starting corner
