An algorithm is a procedure used for solving a problem or performing a computation. Algorithms act as an exact list of instructions that conduct specified actions step by step in either hardware- or software-based routines. Algorithms are widely used throughout all areas of IT.
One thing to keep in mind is that understanding “how those algorithms are used in real-world systems” is generally more important than the implementation details in a system design interview.
An algorithm, in simple words, is a step-by-step set of instructions or a clear and precise set of rules to solve a particular problem or accomplish a specific task. It's like a recipe that guides you through a series of well-defined actions to achieve a desired outcome.
