Q2. 
BFS Traversal in a Graph
Given an undirected and disconnected graph G(V, E) where V vertices are numbered from 0 to V-1, and E represents edges, your task is to output the BFS traversal starting from the ...read more
Ans. 
BFS traversal in a disconnected graph starting from vertex 0.
• Use BFS algorithm to traverse the graph starting from vertex 0.

• Explore neighbor nodes first before moving to the next level neighbors.

• Consider bidirectional edges in an undirected graph.

• Output the BFS traversal sequence for each test case in a separate line.

• Ensure the BFS path starts from vertex 0 and print connected nodes in numerical sort order.

Sort a given stack in ascending order using only push and pop operations with the help of an additional stack.
• Use one additional stack to assist in sorting the elements.

• Pop elements from the input stack and push them onto the auxiliary stack in sorted order.

• Keep track of the current minimum element to maintain ascending order.

• Pop elements from the auxiliary stack back to the input stack to get the sorted order.

Ans. 
Find the largest palindrome number strictly less than a given palindrome number.
• Iterate from the middle towards the start of the number and decrement the digits to create the largest palindrome less than the given number.

• Handle cases where the number is all '9's by changing the middle digit to '9' and decrementing the rest of the digits.

• If the number has an odd length, simply mirror the first half to create the largest

1st was logical reasoning 2nd was aptitude test

General aptitude. Around 2-3 questions with fixed time limit.

Coding for 2-3 questions. Any coding language knowledge is a must to clear this. Failing to clear doesn't guarantee your rejection.

This is the deciding round where you are given logical questions one by one. You dont need coding language knowledge as long as you are able to portray the logic using a flowchart.

I applied through a job fair ,had one apti question followed by the selection was 2 more apti questions and a coding round 3 questions either pattern printing,matrix questions or sliding window.

After clearing the prev round I had an HR interview followed by one more coding round ,this time questions were hard.

The same day,I had a departmental round where I had to work in the office with a supervisor assigned to me and finish some tasks and assignments.

Q1. Focus on the Database questions and Your related technologies. Just clear your basics and provide examples based on explanation.
