ACID properties ensure data integrity in DBMS: Atomicity, Consistency, Isolation, Durability.
Atomicity ensures that all operations in a transaction are completed successfully or none at all.
Consistency ensures that the database remains in a consistent state before and after the transaction.
Isolation ensures that multiple transactions can be executed concurrently without affecting each other.
Durability ensures that once...
I applied via Campus Placement and was interviewed in Jun 2024. There was 1 interview round.
This was my first campus drive,& it was one of the hardest one too.We had 3 coding problems for 60 mins.It was held on HackerRank & it was not so hard but not so easy for the beginners.
1)Lambda Sort
2) and 3) ques on SQL
It was different ques for each one.

Overloading is having multiple methods with the same name but different parameters. Overriding is implementing a method in a subclass that is already defined in the parent class.
Overloading allows a class to have multiple methods with the same name but different parameters.
Overriding occurs when a subclass provides a specific implementation of a method that is already provided by its parent class.

Primary key uniquely identifies a record in a table, while unique key ensures all values in a column are distinct.
Primary key does not allow NULL values, while unique key allows one NULL value.
A table can have only one primary key, but multiple unique keys.
Primary key is a combination of unique and not null constraints.
Primary key is used to establish relationships between tables, while unique key is used to enforce un
I was interviewed before Feb 2024.
There were two coding questions; one was related to linked lists, and the other was linked to binary trees.
Developed a web application for tracking inventory and sales data
Used React for front-end development
Implemented RESTful APIs using Node.js and Express for back-end
Utilized MongoDB for database management
Integrated authentication and authorization features for secure access
Implemented data visualization using Chart.js
Reversing a linked list involves changing the direction of pointers to go from the end to the beginning.
Start by initializing three pointers: current, previous, and next.
Iterate through the linked list, updating the pointers to reverse the direction of the links.
Update the head of the linked list to point to the new first node, which was the original last node.
Program to find perfect squares between two numbers
Iterate through numbers between the given range
Check if the square root of the number is an integer
If yes, then it is a perfect square
Smart pointers in C++ are objects that act like pointers but provide automatic memory management.
Smart pointers help prevent memory leaks by automatically managing memory allocation and deallocation.
Examples include unique_ptr, shared_ptr, and weak_ptr.
unique_ptr is used for exclusive ownership, shared_ptr for shared ownership, and weak_ptr to prevent circular references.
Mutual exclusion is a concept in concurrent programming where only one thread can access a shared resource at a time.
Ensures that only one thread can access a critical section of code at a time
Prevents race conditions and data corruption
Commonly implemented using locks, semaphores, or mutexes
Example: Using a mutex to protect a shared variable in a multi-threaded application
Implementing multithreading involves creating and managing multiple threads to execute tasks concurrently.
Identify the tasks that can be executed concurrently
Create and manage multiple threads to execute these tasks simultaneously
Use synchronization techniques like locks and semaphores to prevent race conditions
Handle communication and coordination between threads
Consider thread safety and resource sharing issues
Search for a target value in a 2D matrix efficiently.
Use binary search on rows to find the potential row where the target value may exist.
Then use binary search on that row to find the target value.
Find quadraplets in an array that sum up to a target value.
Use a nested loop to iterate through all possible combinations of quadraplets.
Keep track of the sum of each quadraplet and compare it to the target value.
Return the quadraplets that match the target sum.

General Aptitude Questions
The shape of a normal distribution is bell-shaped and symmetrical.
A normal distribution has a peak at the mean and tails that extend to infinity in both directions.
The distribution is symmetrical, meaning that the left and right halves mirror each other.
The standard deviation determines the spread or width of the distribution.
Many natural phenomena and measurements in various fields follow a normal distribution.
Example...
Mean, median, and mode are measures of central tendency in statistics.
Mean is the average of a set of numbers, calculated by summing all the values and dividing by the total count.
Median is the middle value in a sorted list of numbers. If there is an even number of values, it is the average of the two middle values.
Mode is the value that appears most frequently in a set of numbers. It can be a single value or multiple

Stacks are a data structure that follows the Last In First Out (LIFO) principle.
Elements are added and removed from the top of the stack
Common operations include push (add element) and pop (remove element)
Stacks can be implemented using arrays or linked lists
Examples of stack usage include function call stack and undo/redo functionality in text editors
To find the middle number in a linked list.
Traverse the linked list using two pointers, one moving twice as fast as the other.
When the fast pointer reaches the end, the slow pointer will be at the middle node.
If the linked list has even number of nodes, there will be two middle nodes. Return either one.
