Efficiently locate an element in a sorted 2D matrix using binary search or a stair-step approach.
Use binary search on each row if the matrix is sorted row-wise.
For a matrix sorted both row-wise and column-wise, start from the top-right corner.
If the current element is greater than the target, move left; if less, move down.
Example: In a matrix [[1, 2, 3], [4, 5, 6], [7, 8, 9]], to find 5, start at 3 (top-right) and...
A binary tree is balanced if the height of its left and right subtrees differ by at most 1.
A balanced binary tree has a smoother and faster search time than an unbalanced one.
Balancing a binary tree can be done using various algorithms like AVL tree, Red-Black tree, etc.
An example of a balanced binary tree is the AVL tree, where the heights of the left and right subtrees differ by at most 1.

MVC components include Model, View, and Controller for organizing code in a web application.
Model: Represents the data and business logic of the application.
View: Represents the UI and presentation layer of the application.
Controller: Acts as an intermediary between Model and View, handling user input and updating the Model accordingly.
Example: In a web application, a user interacts with the View (UI), which sends...

Filters in MVC are components that allow pre-processing and post-processing of requests and responses.
Filters are used to perform common functionalities like logging, authentication, authorization, etc.
They can be applied globally to all controllers or selectively to specific controllers or actions.
Examples of filters include Authorization filters, Action filters, Result filters, and Exception filters.

Yes, it is possible to import the same class or package twice in Java, but it will not cause any issues during runtime.
Importing the same class or package multiple times in Java will not result in any errors or conflicts.
The Java compiler will simply ignore duplicate imports and only include the class or package once in the compiled code.
This behavior helps in avoiding unnecessary redundancy and keeps the code cle...
Marker interfaces in Java are interfaces with no methods, used to mark classes for special treatment.
Marker interfaces have no methods, they simply mark a class as having a certain capability or characteristic.
Examples of marker interfaces in Java include Serializable, Cloneable, and Remote.

Not for just this round but after every round think of some questions you want to ask the interviewer and have them at the back of your mind. When given the opportunity ask them. Don't ask just for the sake of asking. Everyone has some genuine questions to ask, just think over them and ask them later on.

15 Questions
- Q1. Find Minimum and Maximum of an array in only one traversal
- Ans.
Find the minimum and maximum values in an array in a single traversal.
Initialize min and max variables with the first element of the array
Iterate through the array and update min and max if a smaller or larger value is found
Return the min and max values
- Q2. Given a chessboard find the maximum number of squares present?
- Ans.
The maximum number of squares on a chessboard is 64.
The chessboard has 64 squares in total.
The number of squares on a chessboard can be calculated using the formula n^2, where n is the number of rows or columns.
In this case, n = 8 (8 rows and 8 columns), so the maximum number of squares is 8^2 = 64.
- Q3. What is C++? Difference between deep and shallow copy?
- Ans.
C++ is a programming language. Deep copy creates a new object and copies all values, while shallow copy creates a reference to the original object.
C++ is a general-purpose programming language
Deep copy creates a new object with its own copy of the data
Shallow copy creates a reference to the original object
Deep copy is safer but can be slower and consume more memory
Shallow copy is faster but can lead to unexpected behav...
- Q4. What is pre initialization ?
- Ans.
Pre initialization refers to the process of initializing variables or objects before they are used in a program.
Pre initialization helps avoid errors or unexpected behavior caused by using uninitialized variables.
It is a good practice to pre initialize variables with default values.
Pre initialization can be done using constructors, default values, or initialization blocks.
Example: int count = 0; initializes the variabl...
- Q5. Reverse a linked list with and without using Recursion
- Ans.
Reverse a linked list with and without using Recursion
Iterative approach: Use three pointers to reverse the links between nodes
Recursive approach: Recursively reverse the rest of the list and then fix the links
- Q6. Copy constructor?
- Ans.
A copy constructor creates a new object as a copy of an existing object, ensuring proper resource management.
Used to initialize an object using another object of the same class.
Syntax: ClassName(const ClassName &obj) { /* copy data */ }
Example: MyClass obj1; MyClass obj2 = obj1; // Calls copy constructor
Important for classes that manage dynamic memory to avoid shallow copies.
Default copy constructor performs a shal...
- Q7. Different types of polymorphism, the diamond problem, and how can it be avoided?
- Ans.
Polymorphism refers to the ability of an object to take on many forms. The diamond problem occurs in multiple inheritance.
Polymorphism can be achieved through method overloading and method overriding.
Method overloading allows multiple methods with the same name but different parameters.
Method overriding occurs when a subclass provides a specific implementation of a method already defined in its superclass.
The diamond p...
- Q8. Questions about Virtual
- Q9. Template classes
- Q10. Write a program for an operator(=) such that it behaves differently for integer and character
- Ans.
The program should differentiate between integers and characters when using the assignment operator (=).
Check the data type of the variable before assigning a value.
Use conditional statements to perform different actions based on the data type.
For integers, assign the value directly. For characters, convert the character to its ASCII value and assign it.
- Q11. Given an array, sort the zeroes from non zeros for example Input: 1 2 0 0 7 4 42 0 0 0 6 Output: 1 2 7 4 42 6 0 0 0 0 0
- Ans.
Sort an array by moving all zeroes to the end.
Iterate through the array and move all non-zero elements to the front.
Count the number of zeroes encountered and append them at the end of the array.
Use two pointers to swap elements and maintain the order.
- Q12. Class hierarchy, List the number of VTables created
- Ans.
The number of VTables created in a class hierarchy depends on the number of virtual functions and the number of derived classes.
VTables are used in object-oriented programming languages to implement dynamic dispatch.
Each class with at least one virtual function has its own VTable.
Derived classes inherit the VTable of their base class and add their own entries for any additional virtual functions.
The total number of VTa...
- Q13. When to use List and Vector of Standard Template Library ?
- Ans.
List is preferred when frequent insertion and deletion is required. Vector is preferred when random access is required.
List is implemented as a doubly-linked list, allowing for efficient insertion and deletion at any position.
Vector is implemented as a dynamic array, allowing for efficient random access.
Use List when the number of elements is expected to change frequently and the order of elements matters less.
Use Vect...
- Q14. Given a string “I LOVE CODING”, print “CODING LOVE I”
