Theoretical Questions for Coding Interviews on Basic Data Structures 1. What is a Data Structure? A data structure is a way of organizing and storing data so that it can be accessed and modified efficiently. Common data structures include arrays, linked lists, stacks, queues, and trees. 2. What is an Array? An array is a collection of elements, each identified by an index. It has a fixed size and stores elements of the same type in contiguous memory locations. 3. What is a Linked List? A linked list is a linear data structure where elements (nodes) are stored non-contiguously. Each node contains a value and a reference (or link) to the next node. Unlike arrays, linked lists can grow dynamically. 4. What is a Stack? A stack is a linear data structure that follows the Last In, First Out (LIFO) principle. The most recently added element is the first one to be removed. Common operations include push (add an element) and pop (remove an element). 5. What is a Queue? A queue is a linear data structure that follows the First In, First Out (FIFO) principle. The first element added is the first one to be removed. Common operations include enqueue (add an element) and dequeue (remove an element). 6. What is a Binary Tree? A binary tree is a hierarchical data structure where each node has at most two children, usually referred to as the left and right child. It is used for efficient searching and sorting. 7. What is the difference between an array and a linked list? Array: Fixed size, elements stored in contiguous memory. Linked List: Dynamic size, elements stored non-contiguously, each node points to the next. 8. What is the time complexity for accessing an element in an array vs. a linked list? Array: O(1) for direct access by index. Linked List: O(n) for access, as you must traverse the list from the start to find an element. 9. What is the time complexity for inserting or deleting an element in an array vs. a linked list? Array: Insertion/Deletion at the end: O(1). Insertion/Deletion at the beginning or middle: O(n) because elements must be shifted. Linked List: Insertion/Deletion at the beginning: O(1). Insertion/Deletion in the middle or end: O(n), as you need to traverse the list. 10. What is a HashMap (or Dictionary)? A HashMap is a data structure that stores key-value pairs. It allows efficient lookups, insertions, and deletions using a hash function to map keys to values. Average time complexity for these operations is O(1).

Evolution of Programming Languages 🖥️ 🔰Programming Languages🔰 1. JAVA: More than 85% android apps are created using JAVA. It is also used in big (big means big) websites. It is a portable programming language which makes it easy to use on multi platforms. 2. Java Script: Its a browser/client side language. It makes the webpage more interactive. Like for example when you enter a comment on Facebook then the whole page doesn’t load., just that comment is added. This kind of functionalities are added into webpages with JavaScript. Javascript brought about a revolution in webapps. 3. Assembly Language: The most low level programming language because its nothing more than machine code written in human readable form. Its hard to write and you need to have deep understanding of computers to use this because you are really talking with it. Its very fast in terms of execution. 4. C: Its a low level language too that’s why its fast. It is used to program operating system, computer games and software which need to be fast. It is hard to write but gives you more control of your computer. 5. C++ : Its C with more features and those features make it more complex. 6. Perl: A language which was developed to create small scripts easily . Programming in Perl is easy and efficient but the programs are comparatively slower. 7. Python: Perl was made better and named Python. Its easy, efficient and flexible. You can automate things with python in a go. 8. Ruby: Its similar to Python but it became popular when they created a web application development framework named Rails which lets developers to write their web application conveniently. 9. HTML and CSS: HTML and CSS are languages not programming languages because they are just used display things on a website. They do not do any actual processing. HTML is used to create the basic structure of the website and then CSS is used to make it look good. 10. PHP: It is used to process things in a website. It is server-sided language as it doesn’t get executed in user browser, but on the server. It can be used to generate dynamic webpage content. 11. SQL: This is not exactly a programming language. It is used to interact with databases. ➡️ This list could be long because there are too many programming language but I introduced you to the popular ones. ❓Which Language Should Be Your First Programming Language? ✅ Suggestions.. 1. Getting Started Learn HTML & CSS. They are easy and will give you a basic idea of how programming works. You will be able to create your own webpages. After HTML you can go with PHP and SQL, so will have a good grasp over web designing and then you can go with python, C or Java. I assure you that PHP, HTML and SQL will be definitely useful in your hacking journey. 2. Understanding Computer And Programming Better C..The classic C! C is one of the most foundational languages. If you learn C, you will have a deep knowledge of Computers and you will have a greater understanding of programming too, that will make you a better programmer. You will spend most of your time compiling though (just trying to crack a joke). 3. Too Eager To Create Programs? Python! Python is very easy to learn and you can create a program which does something instead of programming calculators. Well Python doesn’t start you from the basics but with if you know python, you will be able to understand other languages better. One benefit of python is that you don’t need to compile the script to run it, just write one and run it. React ❤️ for more
