I appeared for an interview before Apr 2021.

Round 1 - Coding Test 

(2 Questions)

Round duration - 75 minutes
Round difficulty - Medium

This was an online coding round where I had 2 questions to solve under 75 minutes. Both the coding questions were of Medium to Hard level of difficulty.

  • Q1. 

    Smallest Window Problem Statement

    Given two strings, S and X, your task is to find the smallest substring in S that contains all the characters present in X.

    Example:

    Input:
    S = "abdd"
    X = "bd"
    Output:
    ...
  • Ans. 

    Find the smallest substring in S that contains all characters in X.

    • Use a sliding window approach to find the smallest substring in S that contains all characters in X.

    • Keep track of the characters in X using a hashmap.

    • Move the window by adjusting the start and end pointers until all characters in X are found.

    • Return the smallest substring encountered.

    K - Sum Path In A Binary Tree

    Given a binary tree where each node contains an integer value, and a value 'K', your task is to find all the paths in the binary tree such that the sum of the node values in ...

  • Ans. 

    Find all paths in a binary tree where the sum of node values equals a given value 'K'.

    • Traverse the binary tree using DFS and keep track of the current path and its sum.

    • At each node, check if the current sum equals 'K' and add the path to the result.

    • Continue traversal to the left and right child nodes recursively.

    • Return the list of paths that sum up to 'K'.

    Validate Partial Binary Search Tree (BST) Problem Statement

    You are provided with a binary tree containing 'N' nodes. Your task is to determine if this tree is a Partial Binary Search Tree (BST). Return t...

  • Ans. 

    Validate if a binary tree is a Partial Binary Search Tree (BST) by checking if each node's left subtree contains nodes with data less than or equal to the node's data, and each node's right subtree contains nodes with data greater than or equal to the node's data.

    • Check if each node's left subtree follows BST property (data <= node's data) and right subtree follows BST property (data >= node's data)

    Given an array of integers with 'N' elements, determine the length of the longest subsequence where each element is greater than the previous element. This...

  • Ans. 

    Find the length of the longest strictly increasing subsequence in an array of integers.

    • Use dynamic programming to solve this problem efficiently.

    • Initialize an array to store the length of the longest increasing subsequence ending at each index.

  • Q3. Can you define process and threads in operating systems?
  • Ans. 

    Processes are instances of a program in execution, while threads are lightweight processes within a process.

    • A process is a program in execution, with its own memory space and resources.

    • Threads are lightweight processes within a process, sharing the same memory space and resources.

    • Processes are independent of each other, while threads within the same process can communicate and share data.

  • Q4. What are the different types of semaphores?
  • Ans. 

    Different types of semaphores include binary semaphores, counting semaphores, and mutex semaphores.

    • Binary semaphores: Can only have two states - 0 or 1. Used for mutual exclusion.

    • Counting semaphores: Can have multiple states. Used for managing resources with limited capacity.

    • Mutex semaphores: Similar to binary semaphores but with additional features like priority inheritance.

(3 Questions)

Round duration - 60 Minutes
Round difficulty - Hard

In this round, I was asked 3 coding questions out of which I had to implement the first two and for the last question I was only asked the optimal approach. The main challenge in this round was to implement the first two questions in a production ready manner without any bugs and so I had to spent some time thinking about some Edge Cases which were important with respect to the question.

  • Ans. 

    The task is to find the next greater element for each element in an array to its right, if no greater element exists, return -1.

    • Use a stack to keep track of elements for which the next greater element is not found yet.

    • Iterate through the array from right to left and pop elements from the stack until a greater element is found.

    • Store the next greater element for each element in a separate array.

  • Ans. 

    Generate power set of a sorted array of integers with individually sorted subsets.

    • Use recursion to generate all possible subsets by including or excluding each element in the array.

    • Sort each subset before adding it to the power set.

    • Handle base case when all elements have been considered to add the subset to the power set.
