  • \$\begingroup\$ @Bbrk24 Except for rabbit, they're animals documented to be able to count. Bee ๐Ÿ is output via number of matches, because counting that is fairly lightweight to implement in most languages (bees are small). Elephant ๐Ÿ˜ is output via capture count, because that is in a way kind of overkill (elephants are big), since in .NET a capture stack contains the contents of its captures, which is potentially much more information than just the number of captures. Rabbit ๐Ÿ‡ is output via number of ways it can match, because rabbits multiply (breed), and this output method is great at multiplying. \$\endgroup\$ Commented Apr 14, 2023 at 20:32
  • \$\begingroup\$ @Bbrk24 The reason I use emojis for those output methods is to differentiate them from output via the length of a string. Depending on the challenge, it can be a very different, or sometimes even impossible, to output via the length of a string instead of the count of something. Trivially it's impossible to output a number larger than the input without using a counting-style output, but also there are ones like totient function in ECMAScript where it's much more complicated and interesting to output via string length than some type of count. \$\endgroup\$ Commented Apr 14, 2023 at 20:33
