Jude is solving his problem by the use of:.a) trial and errorb) the availability heuristicc) the representativeness heuristicd) an algorithme) confirmation bias

D. An algorithm.

Explanation:

In this scenario, rather than using a shortcut to find various possible combinations of, Jude systematically lists every possible combination to determine the correct code. Jude is solving his problem by the use of an algorithm.

An algorithm can be defined as a finite set of rules or systematic procedures used by an individual for performing a task or solving a problem.
