Model in Laravel is a PHP class that interacts with a database table.
Models are used to retrieve and store data in a database.
They represent a table in the database and define its structure.
Models can have relationships with other models.
They can also have methods for performing common database operations.
Laravel provides an ORM (Object-Relational Mapping) to work with models.
MVC stands for Model-View-Controller, a software design pattern used for developing web applications.
MVC separates an application into three interconnected components: Model, View, and Controller.
Model represents the data and business logic of the application.
View is responsible for rendering the user interface.
Controller handles user input and updates the model and view accordingly.

Laravel's ORM is called Eloquent and it provides a simple and elegant syntax for working with databases.
Eloquent allows developers to define relationships between database tables using model clas...
Many to many relationships refer to a situation where multiple instances of one entity are related to multiple instances of another entity.
It involves three tables: two entities and a junction table
Example: A student can enroll in multiple courses and a course can have multiple students enrolled
The junction table will have foreign keys from both entities
To fetch 1st, 2nd, 3rd rank from student mark table, we need to sort the table in descending order and select the top 3 rows.
Sort the student mark table in descending order based on the marks column.
Select the top 3 rows from the sorted table.
The first row will have the highest marks and hence the first rank, second row will have the second highest marks and hence the second rank, and so on.
An array is a collection of similar data types stored in contiguous memory locations.
Arrays can be of different types such as integer, float, character, etc.
For example, int arr[5] is an array of 5 integers.
Another example is char str[10] which is an array of 10 characters.
Arrays can also be multidimensional, such as int arr[3][4] which is a 3x4 matrix of integers.

An annotation for controller in software engineering.
The annotation for controller is used to define the class as a controller in a software application.

The 'shift' method removes the first element from the array.
The 'final' keyword in Java is used to declare constants, prevent method overriding, and ensure thread safety.
Final variables cannot be reassigned once initialized
Final methods cannot be overridden by subclasses

Final parameters ensure that they cannot be modified within a method
Final fields can be used to achieve thread safety
The question is about method overloading in Java.
Method overloading allows multiple methods with the same name but different parameters.
The method to be called is determined at compile-time based on the arguments passed.
In the given code, there are three overloaded methods with the same name 'getsum'.
The first method takes two integers as arguments.
The second method takes three integers as arguments.
The third method ta...
The program will result in a StackOverflowError due to infinite recursion.
The 'floating' method is recursively calling itself without a base case to stop the recursion.
Each recursive call multiplies the input parameter by the result of the recursive call with a decremented parameter.
This will continue indefinitely until the stack overflows and an error is thrown.
The output of the code is 9.
The code initializes i as 0 and j as 10.
Inside the do-while loop, i is incremented by 1 and j is decremented by 1.
The loop continues until i becomes greater than or equal to j.
Since i is incremented before the comparison and j is decremented before the comparison, the loop runs 9 times.
Therefore, the output is 9.
I was interviewed before Apr 2021.
