Merge Sort is a divide and conquer algorithm that divides the input array into two halves, sorts them recursively, and then merges them back together.
Divide the array into two halves
Recursively sort each half
Merge the sorted halves back together
Time complexity is O(n log n)
Example: [38, 27, 43, 3, 9, 82, 10] -> [38, 27, 43] [3, 9, 82, 10] -> [38, 27] [43] [3, 9] [82, 10] -> [27, 38] [43] [3, 9] [10, 82] ->
Basic JPA construction involves creating entity classes, defining relationships, and configuring persistence settings.
Create entity classes with @Entity annotation
Define relationships between entities using @OneToOne, @OneToMany, @ManyToOne, @ManyToMany annotations
Configure persistence settings in persistence.xml file
Use EntityManager to interact with the database
Arrays store elements in contiguous memory locations, while linked lists store elements in nodes with pointers to the next node.
Arrays have constant time access to elements using index, while linked lists have linear time access.
Arrays have fixed size, while linked lists can dynamically grow and shrink.
Insertions and deletions are faster in linked lists as compared to arrays.
Example: Array - ['apple', 'banana', 'cherry
I applied via Referral and was interviewed in Nov 2024. There was 1 interview round.
HTTP protocol is a set of rules for transferring data over the internet. Request parameters are data sent with an HTTP request.
HTTP protocol stands for Hypertext Transfer Protocol and is used for communication between web servers and clients.
Request parameters are key-value pairs sent in the URL or body of an HTTP request to provide additional information to the server.
Example: In a GET request, parameters can be inclu
Fetching from services and repositories involves making API calls to retrieve data.
Use HTTP requests to communicate with services and repositories
Utilize libraries like Axios or Fetch for making API calls
Handle responses asynchronously to retrieve data
Parse and process the data received from services and repositories
Implement error handling for failed requests

You are given a grid containing oranges where each cell of the grid can contain one of the three integer values:
Find the minimum time required to rot all fresh oranges in a grid.
Use Breadth First Search (BFS) to simulate the rotting process.
Track the time taken to rot all oranges and return -1 if any fresh oranges remain.
Handle edge cases like no fresh oranges or all oranges already rotten.
Consider using a queue to efficiently process adjacent oranges.
Ensure to update the grid with the new state of oranges after each second.
Given a natural number N
, return the sum of all its proper divisors.
A proper divisor of Y
is defined as a number X
such that X < Y
and Y % X = 0
.
T...
Calculate the sum of proper divisors of a given natural number.
Iterate from 1 to sqrt(N) and check for divisors
If a divisor is found, add it to the sum and also add N/divisor if it is not the same as divisor
Return the sum as the result

Technical interview
Given an array ARR
consisting of non-negative integers, rearrange the numbers to form the largest possible number. The digits within each number cannot be changed.
Rearrange the array elements to form the largest possible number by concatenating them.
Sort the array elements in a custom comparator function to get the largest number.
Convert the sorted array elements to strings and concatenate them to form the final number.
Handle cases where the numbers have the same prefix by comparing the concatenated forms.
Tip 1 : Be clear about whatever you have mentioned in resume, don't mention buzz words, because interviewer can go in depth
Tip 2 : Along with DS and Algo, if you have 3-4 months experience or internship experience, then be ready to answer scenario based technical questions like scaling the application that you developed and design concepts that can be used for improving
Tip 3 : Last but most important tip is to be calm through out the whole process ,don't loose hope if any round didn't go well ,if you have explained your thought process there is still chance to procees to next round so keep preparating for next rounds.
Tip 1 : Keep it one page resume and mention keywords which align with your technical and personal competencies.
Tip 2 : Mention 3-4 projects in the order that , project which you can explain best should be at top,then the next, and so on.
