Top 10 Questions for Dunner Interview

1. What are the different types of data structures you have worked with?

• Arrays
• Linked lists
• Stacks
• Queues
• Trees
• Graphs

2. What is the time complexity of searching for an element in a balanced binary search tree?

• The time complexity of searching for an element in a balanced binary search tree is O(log n), where n is the number of elements in the tree.
• This is because the tree is balanced, which means that the height of the tree is O(log n).
• As a result, the worst-case time complexity for searching for an element is O(log n).

3. What is the difference between a hash table and a binary search tree?

• A hash table is a data structure that stores key-value pairs.
• The key is used to quickly access the value.
• A binary search tree is a data structure that stores data in a sorted order.
• The data is stored in nodes, and each node has a key and a value.
• The key is used to compare the nodes and determine their order in the tree.

4. What is the difference between a stack and a queue?

• A stack is a data structure that follows the last-in, first-out (LIFO) principle.
• This means that the last element added to the stack is the first element to be removed.
• A queue is a data structure that follows the first-in, first-out (FIFO) principle.
• This means that the first element added to the queue is the first element to be removed.

5. What is the difference between a graph and a tree?

• A graph is a data structure that consists of a set of nodes and a set of edges.
• The nodes represent the data, and the edges represent the relationships between the data.
• A tree is a special type of graph that has no cycles.
• This means that there is no path from any node back to itself.

6. What is the difference between a shallow copy and a deep copy?

• A shallow copy creates a new object that is a copy of the original object.
• However, the new object only contains the values of the original object, not the objects that the original object references.
• A deep copy creates a new object that is a copy of the original object, including all of the objects that the original object references.

7. What is the difference between a constructor and a method?

• A constructor is a special method that is called when an object is created.
• The constructor is used to initialize the object’s properties.
• A method is a function that is defined within a class.
• Methods are used to perform operations on the object.

8. What is the difference between a class and an interface?

• A class is a blueprint for creating objects.
• A class defines the properties and methods that objects of that class will have.
• An interface is a contract that defines the methods that a class must implement.
• Interfaces do not define any properties or methods themselves.

9. What is the difference between a package and a module?

• A package is a collection of related classes and interfaces.
• Packages are used to organize code and make it easier to maintain.
• A module is a single unit of code that can be imported into other programs.
• Modules are used to share code between different programs.

10. What is the difference between a library and a framework?

• A library is a collection of pre-written code that can be used to perform common tasks.
• Libraries are typically used to add functionality to a program without having to write the code yourself.
• A framework is a set of pre-written code that provides a structure for building an application.
• Frameworks are typically used to speed up development and reduce the amount of code that you have to write.
