Polymorphism is the ability of a single function or method to operate on different types of data.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
There are two types of polymorphism: compile-time (method overloading) and runtime (method overriding).
Example: Animal superclass with subclasses Dog and Cat. Both Dog and Cat can be treated as Animals.
Heap memory is used for dynamic memory allocation, while stack memory is used for static memory allocation.
Heap memory is used for storing objects and is managed by the JVM, while stack memory is used for storing method calls and local variables.
Heap memory is larger in size compared to stack memory.
Objects stored in heap memory can be accessed globally, while variables in stack memory are only accessible within the sc...

Lookup is used to perform a left outer join in MongoDB, while graphlookup is used to perform recursive graph traversal.
Lookup is used to perform a left outer join between two collections in MongoDB.
Graphlookup is used to perform recursive graph traversal in a collection that contains graph data.
Lookup can only perform a single level join, while graphlookup can perform multiple levels of traversal.
Lookup is faster than
Use a hashmap to count the frequency of each character in a string.
Create a hashmap to store characters as keys and their frequencies as values.
Iterate through the string and update the hashmap accordingly.
Return the hashmap with character frequencies.

To implement a queue using a stack, use two stacks and simulate the queue operations.
Use two stacks, one for enqueue operation and one for dequeue operation.
For enqueue operation, simply push elements onto the stack used for enqueueing.
For dequeue operation, if the dequeue stack is empty, pop all elements from enqueue stack and push onto dequeue stack.
Then pop from the dequeue stack to simulate dequeue operation.
A linked list is a data structure consisting of nodes where each node points to the next node in the sequence.
Create a Node class with data and next pointer
Initialize a head pointer to null
Add nodes by updating next pointers
Traverse the list by following next pointers
I applied via Campus Placement and was interviewed in Jun 2024. There were 2 interview rounds.
It was ok. I was not able to solve all the questions.
To remove the last element from a linked list, iterate to the second last node and update its next pointer to null.
Iterate through the linked list to find the second last node
Update the next pointer of the second last node to null

Simple question on maths
OOPS (Object-Oriented Programming) is a programming paradigm based on the concept of objects, which can contain data and code.
OOPS focuses on creating objects that interact with each other to solve complex problems
Key principles include encapsulation, inheritance, polymorphism, and abstraction
Encapsulation ensures that the internal state of an object is hidden from the outside world
Inheritance allows a class to inherit...

60mintues DSA level coding exam
I applied via Walk-in and was interviewed in Feb 2022. There were 3 interview rounds.
5 coding questions in 45 mins ...very easy questions, you can easily do..pen paper based exam. Programs were on strings, arrays and patterns
Round 2 is also coding test here questions were moderate. 3 questions given for 1.5 hours..
Again string and pattern programs were given.
Candidate should be clear with loops , strings arrays..thats it.. no need of studying linked lists ,stacks, queues or other data structures..your knowledge of algorithms doesnt matter here..its all about patterns, strings, arrays and loops
It is last coding round..here there is too much politics those who are working there call there friends and make them sit directly in final round..3 questions given no limit on time you have to do any 2 . They will roam around in roam and will discuss your code..they will help there friends as i was there without any referral there was noone for me..but it doesn't matter if u have strong basics u can crack it ..because problems are again on strings, arrays,patterns . I got bored doing same problems.
