Identify and correct two swapped nodes in a Binary Search Tree (BST) to restore its properties.
In a BST, for any node, left children are smaller and right children are larger.
Perform an in-order traversal to identify the two swapped nodes.
During traversal, keep track of the previous node to find violations.
Example: For BST [4, 2, 6, 1, 3, 5, 7], if 1 and 6 are swapped, in-order gives [6, 2, 4, 1, 3, 5, 7].
Swap the...

There are two types of triggers: DML triggers and DDL triggers.
DML triggers are fired in response to DML (Data Manipulation Language) statements like INSERT, UPDATE, DELETE.
DDL triggers are fired in response to DDL (Data Definition Language) statements like CREATE, ALTER, DROP.
Examples: A DML trigger can be used to log changes made to a table, while a DDL trigger can be used to enforce certain rules when a table is alt...
Yes, triggers can be used with select statements in SQL.
Triggers are database objects that are automatically executed in response to certain events, such as insert, update, or delete operations.
While triggers are commonly used with insert, update, and delete statements, they can also be used with select statements.
Using triggers with select statements allows you to perform additional actions or validations before or af...
Indexing in MySQL improves query performance. There are several types of indexing in MySQL.
Indexes are used to quickly locate data without scanning the entire table.
Types of indexing in MySQL include B-tree, hash, full-text, and spatial indexes.
B-tree indexes are the most common and suitable for most use cases.
Hash indexes are used for exact match lookups.
Full-text indexes are used for searching text-based data efficie...
Engines in MySQL are the underlying software components that handle storage, indexing, and querying of data.
MySQL supports multiple storage engines, each with its own strengths and features.

Yes, a constructor can be private.
A private constructor can only be accessed within the class itself.
It is often used in singleton design pattern to restrict object creation.
Private constructors are also useful for utility classes that only contain static methods.

Myntra had conducted a coding test on campus before the start of the placement season with 2 questions, one on stack and other on DP.
Tips : For the test, the DP question asked was pretty standard, on Longest Common Subsequence. The question on stacks, I don't remember what it was but it was also pretty straight forward. For the test, I would recommend to solve problem from GFG. If they do come to resume shortlisting, they are looking for people who have done good projects and internships.

A subsequence is a sequence that can be derived from another sequen...

The interview started off with questions on my general interest in Software Development. The first round had two coding questions, I was supposed to write the code on paper.
For the questions, they asked me to code the solution first. And then gave a specific input and asked me to demonstrate step by step in my code, how it would lead to the correct answer.
Tips: It's ok if you can't code a general solution, if you can write a code which works for the particular input they have given then also it's ok with them. But be thorough with Data structures.
You are given two singly linked lists, where each list represents a positive number without any leading zeros.
Your task is to add these two numbers and return the sum as ...

I wasn't asked to write any code in this interview. They asked me some questions on Machine Learning, because of my projects in them. Then they asked me if I knew graph algorithms. Since I knew BFS and DFS, I told them. They asked the difference between the two. Then they asked me if I knew how to find the shortest distance between two points in a graph. I didn't know Dijkstra's properly but I knew it worked on the greedy approach so was able to tell that. Then they asked me how would I find the second shortest path. I tried to answer it with the same greedy approach, but couldn't arrive at the complete solution.
Tips: They ask a tough theoretical question. It's ok if you don't know the answer, they only look for your approach.
