Great kata! Thanks 😀

.

This isn't an issue. An issue is a bug with a kata. This problem is caused by your code. Your code crashes when the input is an empty vector.

I think this kata should be at level 7, but not at level 6

i get this error over and over

Because not every character is a valid optional nose.

A smiley face can have a nose but it does not have to. **Valid characters for a nose are - or ~**

using the initial value parameter for the reduce method is an elegant way of handling the empty array scenarios. Something new I've learn't today, thanks.

How does this have anything to do with math?

Like for this kind Kata!

Lite ASCII graphic kata!)

please, do not raise issues to ask for help, use questions instead

print your input. your code has false positives, for example it returns 1 for [";~P", "; D"]. neither of these is a valid smiley according to the rule: P is not a valid mouth, and there can be no whitespace between the eyes and the mouth
