Object-oriented programming concepts that focus on classes and objects
Encapsulation: bundling data and methods that operate on the data into a single unit (class)
Inheritance: ability of a class to inherit properties and behavior from another class
Polymorphism: ability to present the same interface for different data types
Abstraction: hiding the complex implementation details and showing only the necessary features

OOPs concept in JAVA is a programming paradigm that focuses on objects and their interactions.
OOPs stands for Object-Oriented Programming
It involves the use of classes, objects, inheritance, polymorphism, and encapsulation
Classes are used to define objects and their properties
Objects are instances of classes that can interact with each other
Inheritance allows for the creation of new classes based on existing ones

Java provides Arrays.sort() method to sort an array.
Use Arrays.sort() method to sort an array of strings.
The method sorts the elements in ascending order by default.
To sort in descending order, use Collections.reverseOrder() method.

I applied via Company Website and was interviewed before Jul 2021. There were 2 interview rounds.
The first round is an aptitude online test that had Basics of Computer Science, Mathematics, English and then finally one basic program to code and compile like Palindrome.
Three panellists were present and it was a face-face round, Panellist 1 and 2 takes the technical discussions like classes, inheritance, oops concept, basic syntax, and such. Panellist 3 talks more about your resume skills, hobbies and the company overview.
To determine if a point is inside a polygon, use the ray casting algorithm.
Create a line from the point to a point outside the polygon
Count the number of times the line intersects with the polygon edges
If the count is odd, the point is inside the polygon; otherwise, it is outside
The four storage classes in C are auto, register, static, and extern.
Auto: default storage class for all local variables
Register: used to define local variables that should be stored in a register instead of RAM
Static: used to define local variables that retain their value between function calls
Extern: used to declare a global variable that is defined in another file
i is stored in global data segment, j is stored in stack, k is stored in heap.
i is a global variable and is stored in the global data segment
j is a local variable and is stored in the stack
k is a pointer variable and is stored in the stack, while the memory it points to is allocated on the heap using malloc()
Use a hash table to store the words and check for existence in constant time.
Create a hash table with the words as keys and a boolean value as the value.
For each new word, check if it exists in the hash table. If it does, it has appeared before. If not, add it to the hash table.
Alternatively, use a set data structure to store only the unique words and check for existence in the set.
I was interviewed in Jul 2017.
Code to print * in five consecutive lines
Use a loop to iterate five times
Inside the loop, print a string containing a single * character
Code to calculate number of bounces a ball goes through until it comes to rest.
Use a loop to simulate the bounces until the ball stops bouncing
Calculate the height of each bounce using the given formula
Keep track of the number of bounces in a counter variable
The best and less time consuming way to calculate factorial of a number is using iterative approach.
Iteratively multiply the number with all the numbers from 1 to the given number
Start with a result variable initialized to 1
Multiply the result with each number in the range
Return the final result
Code to find factorial using function recursion
Define a function that takes an integer as input
Check if the input is 0 or 1, return 1 in that case
Otherwise, call the function recursively with input-1 and multiply it with the input
