Try it without the use of Monad!

Hint: take the invers of digitToInt and the invers of show

oh yeah
btw sorry that i come back to it 1 month later, sorry lol

The best practicle is not use tested function for make test content: if you function got same error it can make false negative test case.

Good Kumite description formalization.

You may make good Kata from this solution.
I found bug when add 2 word of '???' with same text length or case with impossible solving do error "list index out of range".

it basicly counts up every symbol in a string and returns the letter that repeats the same amount of times. if there are some letters that are all repeated the least, it returns the first one that appeared. if the amount of each symbol's repetition is the same, it returns None.

I'm a beginner here. Could anyone tell me what the purpose of this program is?

i think its fixed

oh well, at least it was a fun experience! thank you!

I guess it is, yes.

Not really removed, but if you republish it after you solve the issues, it will most likely get retired, because of the votes of beta testers (who know there are already plenty of this kind of kata).

oh no, so does it mean my kata may be removed? When I was creating the kata it said similar katas may be removed :(

1. means you need to generate var names of random lengths
2. anything about strings evaluation. There are plenty of those, yes.

I just found another one :

currently, you could generate x--50=25 in the random tests. This seems out of the scope of your kata (does your solution even support that kind of cases?) Maybe you should remove all negative numbers from the inputs, rather.

(don't worry about this message, this is just to clear the issue)
