It's wired if this is a real life game.

How do they know they know the subject?

Are they write down all the words they know before the game?

Sample tests have some wrong.

1. The edge test L..... shouldn't be LLLLLL.
2. The balance test input string length is 3002, but the except string length is 3000.

Are there any cases that take a long time to execute (javascript)?

In the basic tests, the longest execution time falls between 30 to 50 ms.

However, I still fail to pass the 12000ms limit.

Additionally, due to the timeout error, I am unable to print anything.

1. Does the lifespan apply only to the mature stage, excluding the piglet phase?
   If so, does that mean the total lifespan from birth to death is 17 and 18 days?
   If not, does that mean the initial pigs are actually 5 days old? Or are they 1 day old and already mature?
2. What is the priority to selecting couples? Older first? Younger first? Boar first? Sow first?
3. What happens if one member of a couple dies? Still need to waiting days? Or instantly can meet next mate?

It's weird to use pigs here.

If no existing species fits your need, you could simply create a new one.

Or just say these pigs are from another planet, so we won't use real life case to think about it.

It's a bit late, but I'm sure someone else has faced this issue too.

This kata requires you to return a String.

Use console.log() to see the input.

Issue tag is for kata issue not your code issue,
you should choose Question to looking for help.

Your checking rules is not what description says, there just 4 rules and you have 5.

Fixed translation here. Need someone to approve.

It has already been approved.

If that, I'll prefer it to be a new kata. Otherwise thanks for replying.

Using enums is a great choice when they are supported.

But on Codewars, you don't get the exact definition of the enum, so you need to guess how to use it.

Is it really a good idea to go with that?

The request ask you to do something, and mark it as important.

After you do that, it says Oh, You don't really need to do that.

Seriously?

Why choose to preload Color in Rust rather than use String, as is commonly done in other languages?
