Another outstanding feature of the functional paradigm is generalization. By this, I mean preferring a general solution over a concrete one, when a concrete problem can be solved by applying a general solution that is accordingly parameterized. Let's turn to our sample problem for evidence of generalization. Adjusting the functional solution to a different length of digit sequences (for example, 8 instead of 5), another math operation on the group (for example, the sum instead of the product), another aggregation property (for example, minimum instead of maximum) are mere changes of parameter values for the correspondent functions. A comparison of how much the code changes will be required in case of the other approaches, which I leave for you as an exercise.
