Which term refers to a series of unambiguous instructions that will yield a solution to a specific problem?

The term "algorithm" refers to a series of unambiguous instructions designed to yield a solution to a specific problem. This concept emphasizes the structured, step-by-step approach to problem-solving in programming and computer science. An algorithm must be clear and defined, providing precise guidance on how to achieve a desired outcome based on a set of inputs.

Algorithms can range from simple arithmetic operations to complex procedures employed in data sorting or searching, allowing various applications in software design and development. The correctness and efficiency of an algorithm play crucial roles in ensuring the desired result is achieved in an optimal manner.

In contrast, a function typically represents a distinct segment of code designed to perform a particular task or return a value but is not necessarily a step-by-step solution to a problem. A procedure can also denote a set series of steps but doesn't inherently convey the structured format required of an algorithm. Lastly, a routine is often synonymous with a function or method in programming, encapsulating tasks but lacking the stringent characteristics that define algorithms in problem-solving contexts. Thus, algorithm is the precise term that encapsulates the essence of methodical problem resolution.
