I appeared for an interview before Jun 2016.
The question asks to construct a k-ary tree using the given k and DFS traversal string.
Iterate through the DFS traversal string
If the current character is 'P', create a parent node
If the current character is 'L', create a leaf node
Link the nodes according to the DFS traversal order
To determine if a graph has a node with n degree, iterate through all nodes and count their edges.
Iterate through each node in the graph
Count the number of edges connected to each node
If any node has n edges, then the graph has a node with n degree
Vector is a dynamic array that can resize itself. It differs from arrays in its ability to change size during runtime.
Vectors are implemented as dynamic arrays, whereas arrays are static.
Vectors can resize themselves during runtime, whereas arrays have a fixed size.
Vectors can be used to store objects of any type, whereas arrays can only store objects of a specific type.
Vectors have built-in functions for easy manipula
An abstract class is a class that cannot be instantiated and is used as a base class for other classes.
An abstract class can have abstract and non-abstract methods.
Abstract methods are declared but not implemented in the abstract class.
A non-abstract class that inherits from an abstract class must implement all abstract methods.
An abstract class can have constructors and fields like a regular class.
An abstract class ca...

This was the qualification round which comprised of several MCQs and 3 coding questions.
It was held on Hackerearth from 3:00 PM to 4:00 PM.
Use of any other IDE was prohibited.
To find and correct a bug in code, analyze problem statement, review code, use debugging tools, and test different scenarios.
Understand the problem statement and expected output.
Review the code for syntax errors, logical errors, and potential bugs.
Use debugging tools like breakpoints, print statements, and IDE debuggers.
Test the code with different inputs to identify the bug.
Make necessary corrections based on the iden...
Given an arbitrary binary tree, a node of the tree, and an integer 'K', find all nodes that are at a distance K from the specified node, and return a list of th...
Given a binary tree, a target node, and an integer K, find all nodes at distance K from the target node.
Traverse the binary tree to find the target node.
Use BFS to traverse the tree from the target node to nodes at distance K.
Keep track of the distance while traversing the tree.
Return the values of nodes at distance K in any order.
Round duration - 90 minutes
Round difficulty - Medium
I was shared a link of Google Meet and the Google Docs was shared where there was 1 coding problem to be coded there and then the code was run on an IDE to check the sample tests.
Then the interview was followed by a lot of Operating System and Computer System Architecture Questions.
There were 2 Interviewers and both were helpful.
The timing was from 2:30 PM to 4:00 PM
Determine the length of the largest subarray within a given array of 0s and 1s, such that the subarray contains an equal number of 0s and 1s.
Input beg...
Find the length of the largest subarray with equal number of 0s and 1s in a given array.
Iterate through the array and maintain a count of 0s and 1s encountered so far.
Store the count difference in a hashmap with the index as the key.
If the same count difference is encountered again, the subarray between the two indices has equal 0s and 1s.
Return the length of the longest subarray found.
Round duration - 45 minutes
Round difficulty - Easy
The round was held on Google Meet with HR from 2:30 PM to 3:15 PM.
The HR was friendly and asked the basic questions.
Tip 1 : Practice daily 4-5 medium level problems on sites like Leetcode, CodeZen, Hackerearth
Tip 2 : Even though Data Structures and Algorithms is the base but study Course Subjects like DBMS,OS,OOPS too.
Tip 3 : Try to Participate in Contests on LeetCode,Codeforces.
Tip 1 : Mention the projects you worked on in your past work experience and how it helped your company.
Tip 2 : Keep your resume up to date in accordance with the role you are applying for
Tip 3 : Don't put false things on your resume.
