Each of a regular dodecahedron's 12 faces can be painted either red or blue. Your task is to implement a function \$f\$ that takes a painted dodecahedron (as 12 booleans, in whatever order and format is convenient) and outputs an identifier (a string or number) to "classify" it. The exact classif...

To save codepoints, a compute-er can share 0 and -, and share . with $(indicating a variable name). A number matches RegEx /^-?(0|[1-9]\d*)(\.\d+)?$/ and a variable matches RegEx /^\$\d+$/. Given input where 0 and - are represented as same char(your choice) and so do . and $, return as number or ...
