Improve resistor-color-duo: map to math #51
Description
Describe the improvement:
When an optimal map solution is provided, the analyzer should approve but provide a comment that allows them to continue the path.
Perhaps there is a solution that does not involve type-juggling: the act of creating a
_string_ of numbers (the digits) and then parsing it back into a number. For example:
what _value_ does the `4` in the number `42` hold.
You may continue with the next exercise, or try out submitting a more math-y solution
and continue here.
Which exercise
resistor-color-duo
Additional context
The ResistorColorDuoAnalyzer has a method that checks if an exercise is optimal. There are various ways to branch based on that optimality. As per the commentary above, using a map is approvable but not optimal.
