Coding Interview Prep: 50 Essential Algorithms

When it comes to preparing for a coding interview, knowing the right algorithms is crucial. In this post, we'll explore the top 50 essential algorithms that you should familiarize yourself with before your next interview. Whether you're a beginner or an experienced developer, these algorithms will help you stand out from the competition and increase your chances of landing your dream job.

Understanding Algorithms

Before we dive into the list, it's essential to understand what an algorithm is. An algorithm is a set of instructions that is used to solve a specific problem or complete a particular task. In the context of coding interviews, algorithms are typically asked to solve a specific problem, and the candidate's job is to write the most efficient and effective code possible. Read more
