Question

Quizplus · Accepted Answer

Robert is using trial-and-error, as he is systematically trying every possible combination until he finds the correct digits. Algorithms involve a specific set of instructions to solve a problem, means-ends analysis involves breaking a problem down into smaller sub-problems, and heuristics involve using shortcuts or rules of thumb to solve a problem.
