Which of the following is a characteristic of a good algorithm?

A good algorithm is characterized by its ability to provide clear instructions for solving a specific problem. Clarity is essential because it allows anyone reading the algorithm—whether they are programmers or not—to understand the steps required to achieve the intended outcome. This characteristic ensures that the algorithm can be correctly implemented, debugged, and modified as needed.

While algorithms can sometimes be complex, their effectiveness is measured not by length or complexity but by their clarity and efficiency. User input is not always necessary for an algorithm; some algorithms operate solely on pre-defined data sets. Additionally, although algorithms can be expressed in various programming languages, the choice of language does not define the quality of the algorithm itself. Ultimately, clear instruction is what allows algorithms to be universally applicable and adaptable, making this the essential characteristic.
