A code challenge is a task or set of tasks designed to assess a programmer's coding skills, problem-solving abilities, and understanding of algorithms and data structures. These challenges are often used in hiring processes, coding competitions, and educational settings to evaluate and improve coding proficiency.
Algorithm design is the process of defining a step-by-step procedure to solve a problem efficiently, optimizing for factors like time and space complexity. It involves understanding the problem requirements, choosing the right data structures, and applying suitable design paradigms to create effective solutions.
Data structures are fundamental constructs that organize and store data efficiently, enabling effective data manipulation and access. Understanding different Data structures and their trade-offs is essential for optimizing algorithms and solving complex computational problems.
Problem solving is the process of identifying a challenge or obstacle and developing effective strategies to overcome it, often involving critical thinking and decision-making skills. It requires a clear understanding of the problem, creative thinking to generate solutions, and the ability to implement and evaluate the chosen solution effectively.
Space complexity refers to the amount of working storage an algorithm needs, considering both the fixed part and the variable part that depends on the input size. It is crucial for evaluating the efficiency of algorithms, especially when dealing with large datasets or limited memory resources.
Software development is the process of designing, programming, testing, and maintaining applications and frameworks resulting in a software product. It involves a series of systematic methodologies and practices to meet user requirements and ensure high-quality software delivery.
Programming languages are formal systems designed to communicate instructions to a computer, enabling the development of software applications and systems. They vary in syntax, paradigm, and level of abstraction, catering to different programming needs and preferences.

Debugging is the process of identifying, analyzing, and fixing bugs or errors in software to ensure it runs correctly and efficiently. It involves a systematic approach to problem-solving, often requiring a deep understanding of the code and the environment in which it operates.
Code optimization is the process of modifying code to improve its efficiency, speed, and performance without altering its output or functionality. It involves various techniques and strategies to reduce resource consumption and enhance execution time, making the code more efficient for both developers and end-users.
Test-Driven Development (TDD) is a software development approach where tests are written before the actual code, ensuring that the codebase is continually validated against its specifications. This iterative process promotes better design, reduces bugs, and facilitates easier code refactoring and maintenance.
PKCE (Proof Key for Code Exchange) is an OAuth 2.0 extension designed to enhance the security of public clients by preventing authorization code interception attacks. It achieves this by using a dynamically generated secret, called a code verifier, which is transformed into a code challenge and verified during the token exchange process.
Proof Key for Code Exchange (PKCE) is an OAuth 2.0 extension designed to enhance the security of public clients by mitigating authorization code interception attacks. It achieves this by using a dynamically generated code verifier and a code challenge to ensure that the authorization code was issued to the same client that is redeeming it.
Concept
PKCE is a way to keep your secret codes safe when you use an app to log in to a website. It makes sure that only the right app can use your special code to get in, even if someone tries to sneak in and take it.
