Binary search is a search algorithm that finds the position of a target value within a sorted array.
Binary search works by repeatedly dividing the search interval in half.
It compares the target value with the middle element of the array.
If the target value matches the middle element, the position is returned.
If the target value is less than the middle element, the search continues on the lower half of the array.
If the ...
An algorithm based on graph is a set of instructions designed to solve problems related to graphs.
Graph algorithms are used to solve problems related to graphs, such as finding the shortest path between two nodes, detecting cycles, and determining connectivity.
Some common graph algorithms include Dijkstra's algorithm for finding the shortest path, Kruskal's algorithm for finding the minimum spanning tree, and Depth Fir...
Scheduling is the process of planning and organizing tasks or resources over a period of time.
Scheduling involves determining the start and end times for tasks or activities.
It helps in optimizing resources and ensuring efficient use of time.
Examples include project scheduling, employee scheduling, and appointment scheduling.
Round robin is a scheduling algorithm that assigns equal time slices to each process in a circular queue.
Each process is given a small unit of time to execute before being moved to the end of the queue.
It ensures fairness by preventing a single process from monopolizing the CPU.
Example: In a round robin scheduling with time quantum of 10ms, processes A, B, and C will each get 10ms of CPU time before moving to the end o

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 and edge cases to identify the bug
Make necessary corrections and re

Find nodes at distance K from target node in a Binary Tree.
Use BFS to traverse the tree and keep track of the distance of each node from the target node.
Maintain a set to keep track of visited nodes to avoid revisiting them.
Return the values of nodes at distance K from the target node.

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.

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 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 atleast 1 project and past work experience as it sets good impression.
Tip 2 : Keep your resume up to date for the role you are applying.
Tip 3 : Try to keep your resume of 1 Page.

The problem involves determining if a string 'C' is formed by interleaving two given strings 'A' and 'B'.
Check if the length of 'C' is equal to the sum of the lengths of 'A' and 'B'.
Verify if all characters of 'A' and 'B' exist in 'C' while maintaining their order.
Return 'True' if 'C' is an interleaving of 'A' and 'B', otherwise return 'False'.

Construct a binary tree from inorder and postorder traversal lists and return its root.
Create a map to store the indices of elements in the inorder traversal list for quick access during tree construction.
Use the postorder list to determine the root of the tree and recursively build left and right subtrees.

Maximize total score by selecting boxes optimally based on power values and operations.
Iterate through the boxes and perform operations based on power values and current score
Keep track of power, score, and selected boxes to maximize total score
Example: For input [3, 50, [20, 30, 40]], select boxes with power 20 and 30 to get a score of 2
Tip 1 : DSA is the key. Starting from scratch, one can become proficients in a couple of months.
Tip 2 : Solve questions just a bit outside your comfort zone. Solve too easy to too hard questions is not of any use.
Tip 3 : Be consistent, make a habit of following good coding practices.
Tip 4 : Get to know the ins and out of your projects. You must be very confident while explaining those.
Tip 5 : Don't just directly to system-design, brush up on OOPS principles, networks, OS, DBMS before that.
Tip 1 : Keep it crisp and to the point. Make bullet points.
Tip 2 : Bold the things you want to be paid attention to. Use numbers rather than vague sentences.
Tip 3 : Only put the things you are confident about.
Tip 4 : Don't put things irrelevant to the job, it only dilutes the main content.
