Haskell fork that fixes that.

I figured it would be something like this but I didn't know the numeric values so I wrote a dictionary lol

I really enjoyed this one! Prime numbers strike again — they never get old. Always fun to revisit them with a new twist!

Haskell:

Description says a and b will both be <= 20000 but the tests expect values beyond that.

Fixed in this fork, re-raised for Haskell

Java:

• method name should be camelCase, not PascalCase

Refer here on how to enable backward compatability to not invalidate all solutions

Same solution

I can see you were trying to pass that last test

I love the simplicity. I need to get on this level of understanding code. Great stuff

Agreed

It might be easier to read when you have pages of code with many different functions.

nice radix conversion from int to string

counting matches of '1' is simple, and could easily scale to higher radixes such as octal
could easily be extended to match multiple digits, such as .count('137')

range traversal is clear

accumulator function sum() over a list is also a nice aggregate function
