MVC architecture pattern segregates an application into Model, View, and Controller components.
Model: represents the data and business logic
View: represents the user interface
Controller: handles user input and updates the model and view accordingly
This pattern helps in separating concerns and makes the code more maintainable and scalable
Examples: Ruby on Rails, ASP.NET MVC, Spring MVC
Stored procedures, packages, functions, and joins are all database concepts used to improve performance and functionality.
Stored procedures are precompiled SQL statements that can be executed multiple times.
Packages are a collection of related procedures, functions, and variables that can be used together.
Functions are similar to stored procedures but return a value.
Joins are used to combine data from multiple tables b
Explaining different types of joins, differences between procedure and function, and index and its types.
Different types of joins are inner join, left join, right join, and full outer join.
Procedure is a set of SQL statements that perform a specific task, while function returns a value.
Index is a data structure that improves the speed of data retrieval operations. Types of index are clustered, non-clustered, unique, an

Check if binary tree is balanced or not.
A balanced binary tree has the height of left and right subtrees differ by at most 1.
Recursively check the height of left and right subtrees and compare.
Use a helper function to calculate the height of a subtree.
Time complexity: O(nlogn) for a balanced tree, O(n^2) for a skewed tree.
Detect loops in a linked list.
Use two pointers, one moving at a faster pace than the other.
If there is a loop, the faster pointer will eventually catch up to the slower one.
To detect the start of the loop, reset one pointer to the head and move both pointers at the same pace.

First they asked me to introduce myself then they started questioning on oops concept from basic to advance level such as inheritance, polymorphism, abstraction, exception handling , STL etc. Next they started questioning on data structures. They asked me the logic of “how to find the middle of a linked list”.
You are provided with a square matrix. Your task is to return true
if the matrix is symmetric; otherwise, return false
.
A symmetric matrix is characterized by its transpose being eq...
Check if a square matrix is symmetric by comparing it with its transpose.
Iterate through the matrix and compare each element with its corresponding element in the transpose
If any pair of elements do not match, return false immediately
If all pairs match, return true at the end
Tip 1 : Clear the basic concepts of data structure and OOPs.
Tip 2 : Use coding ninja platform and Hackerearth for practice on coding skills.
Tip 3 : Use Geeks For Geeks for interview preparation.
