This is not a game I have played in real life, although I have played Mutations with someone, usually while on a long drive somewhere.

It is irrelevant that it is established ahead of time whether or not any player knows any or all of the words in the given subject list. They just do the best they can with their memory banks.

A player would not write out all the four-letter words they know before they play a game. First, it's probably way too many to bother with, and you will not even need most of them most of the time. Futhermore, they will not know which ones they will need, because new words will enter the game when their opponent uses a word from their own memory banks.

I hope that helps!

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.

Spent 2 hours for not reading properly XD

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

This kata requires you to return a String.

I tried to clear up any confusion in the description, it was really hard for me to figure out what I was supposed to do.

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.
