In its current state I would rate this as 7 kyu at most.

Thank you, that's a good spot. It seems I might need to keep an abacus next to me. I've edited the translation.

The random test generator only produces integers in the range -1_000_000, 1_000_001. Sounds like you meant to set the range between -1_000_000_000, 1_000_000_001

Apologies, I only looked at this kata again today. I didn't receive a notification of your comment as it wasn't labeled as Issue.

I'm not sure I follow though, can you expand? I'm trying to understand where the expectation of an i32 comes from.

The solution setup currently takes a u8 for the length parameter and returns u64, so I expected the tests to infer that type and I didn't get any of the above warnings for my own solution either. I'm not sure why yours is returning i32.

fn count_patterns(from: char, length: u8) -> u64 {}

Apologies for pinging you Wisdou, feel free to ignore.

KenKamau, this was a fun kata to solve. I thought I'd give translating this to Rust a shot, but — based on the assumption that the JavaScript version is the original? — there are a couple of parts in the random test that I do not fully understand. I'm hoping you would be willing to explain part of it? To walk you through it, see below:

var leng = "abcdeghijklmnopqrstuvwxyz".repeat(_.random(1, 500)) 

It is my understanding that the above repeats the string abc..xyz by a random amount from [1, 500], as lodash's upper bound is inclusive.

var st = leng[_.random(0, leng.length)]

The variable st seems to hold a random character from the repeated string.

var a = '*' + st, b = st + '*', c = '*' + leng[-1], d = leng[-1] + '*';

This is what I do not understand. I'm not sure what leng[-1] does, as from what I understand this gives one undefined on a String in JavaScript? Was this perhaps supposed to be leng.slice(-1) to get a single character from the String's end?

While taking note of your above feedback, are the Java and C# translations up to par as of right now and can I incorporate code from these into the translation I'm working on?

If there's a better place to discuss this, I'd like to know! I don't think Codewars has a messaging system built in and raising an issue seemed excessive, as it is not related to solving the kata.

Thank you! That's a wonderful post. Bookmarked!

It appears the random tests for JavaScript do not test for negative integers. I've included negative and positive integers in the random tests for Rust, both ten digits long.

Haha, seems we arrived at a nearly identical solution :-)
