Merge two sorted lists with n+m complexity
Create a new list to store the merged result
Iterate through both lists simultaneously and compare elements
Add the smaller element to the new list and move to the next element in that list
Continue until all elements from both lists are merged
Dependency injection is a design pattern where components are given their dependencies rather than creating them internally.
Dependency injection helps in achieving loose coupling between classes.
It allows for easier testing by providing a way to mock dependencies.
There are three types of dependency injection - constructor injection, setter injection, and interface injection.
The n+1 problem in Hibernate occurs when a query results in multiple individual queries being executed for each row fetched.
Occurs when a query fetches a collection and then for each element in the collection, another query is executed to fetch related data
Can be resolved by using fetch joins or batch fetching to reduce the number of queries
Improves performance by reducing the number of database round trips
The code is given to you and you have to solve it

Core Java is a fundamental programming language used for developing software applications. DSA algorithms are essential for efficient problem-solving.
Core Java is used for developing software applications and is based on the Java programming language.
DSA algorithms are data structures and algorithms used for efficient problem-solving.
Examples of DSA algorithms include sorting algorithms like Bubble Sort and searching a
DSA problems involve solving algorithmic challenges, while system design involves designing scalable and efficient software systems.
Practice solving DSA problems on platforms like LeetCode, HackerRank, or CodeSignal.
Study common data structures and algorithms like arrays, linked lists, trees, sorting algorithms, and searching algorithms.
For system design, focus on scalability, reliability, performance, and maintainabil...

6 Objective Questions, 2 Java Coding Question, One Sql query Question 1. Coding: Problem on Josephus Range Game, 2. Coding: Unequal Equal segments.
A program to split an array of strings into smaller arrays based on a given split size.
Iterate through the array and create a new subarray every split size elements
Use array slicing or a loop to extract the subarrays
Handle cases where the split size is larger than the array length
Program to flatten multi dimension Object[] array to Integer[]
Use recursion to iterate through the array and flatten each element
Check if each element is an array or an integer
If it's an array, recursively flatten it
If it's an integer, add it to the result array
I applied via Walk-in and was interviewed in Jul 2023. There were 4 interview rounds.
First round was a coding test on hackerearth. 5 objective, 2 coding and 1 sql question was there. Questions were easy.
Sort a list of cards based on their rank and suit.
Create a custom sorting function that first sorts by rank and then by suit
Use a comparison function to compare ranks and suits of each card
Example: ['2H', '3D', '10S', 'AH', '4C'] should be sorted as ['2H', '3D', '4C', '10S', 'AH']
