Thank you, I ended up figuring out the solution.
Hello,
At the moment I am at a loss here.
I’ve read basically the whole forum thread and I am still confused as why my long game terminates after 1162 rounds with PAT:
An excerpt from my log

If I understood correctly, at the moment P2 wins above battle, the cards are added to his deck (queue-wise) like this:
[battlecardP1+3warcardsP1][battlecardP1+3warcardsP1][winningBattleCard**][battlecardP2+3warcardsP2][battlecardP2+3warcardsP2][losingBattleCard**]
** regardless the player.
As some of the posts contradicts other posts I am not sure what the correct order should be.
Anyone out there that’s able to help me out?
Besides that: cases 7-8-9 fails me.
Whereas when I make some changes sometimes 9 will succeed and 8 keeps failing with the dreaded timeout (e.g. it crashes vscode on my local machine if I try to run it there)
Thanks in advance for any reply.
Regarding your log, which test case is it?
The long game
Bonjour ,
Si les administrateurs l’accepte, ci-joint les commentaires de ma gestion des piles de cartes (ps: mon programme fonctionne 
)
Bon courage.
Hello. I’m getting desperate.
I manage to go past a battle and 2 chain battles but 1 game 1 battle for me is 2 - 212 instead of 1 - 52
Langugage : JavaScript
Concepts:
-
I use same notation replacing J with 11, Q with 12 etc… A is 14. I store them as objects of {v:, n:} for tracking
-
Get 1st card of each array and
shift()the array. In case of a war i will always use the 4-th of the array to compare so it is handy -
The war is handled through recursion:
function war(pp1, pp2, recursionCounter = 1) { //pp1 = Pile Player 1 et
let rCounter = recursionCounter;
//check if the war is possible
if (pp1.length < 4 || pp2.length < 4) {
return "PAT";
}
//war is possible
//take the 4th card, compare
let comp1 = pp1[rCounter * 4 - 1];
let comp2 = pp2[rCounter * 4 - 1];
//if same
if (comp1.v === comp2.v) {
console.error(`consecutive war ${rCounter}`);
rCounter++;
return war(pp1, pp2, rCounter);
} else {
console.error(
`war winner :${
pp1.v > pp2.v ? 1 : 2
} with counter of consequity ${rCounter}`
);
return { winner: pp1.v > pp2.v ? 1 : 2, times: rCounter };
}
}
- Then at the end of the war I assemble the winning pot. The order for it is according to the rules: first the cp1 (1st card player 1 ), followed by n cards from player 1 he used in the war, then cp2 then n cards from war from player 2:
let temp1 = p1.slice(0, warRes.times * 4);
let temp2 = p2.slice(0, warRes.times * 4);
let winPot = [cp1].concat(temp1).concat([cp2]).concat(temp2);
parseInt(warRes.winner) === 1
? (p1 = p1.concat(winPot))
: (p2 = p2.concat(winPot));
- Then the amount of cards used in the battle are deleted from the beginning of the each player’s pile:
function erase(a, n) {
for (let i = 0; i < n; i++) {
a.shift();
}
}
...
//p1 and p2 represent initial pile. As i mentioned, the 1st card for comparison before the battle is already shifted.
erase(p1, warRes.times * 4);
erase(p2, warRes.times * 4);
In the case of 1 game 1 battle, I actually somehow have 6 individual battles.
Can somebody help me with
- Advice
- Log for card amounts after each turn for this particular case
- antidepressants (?)
- Alternative test case where there are less data?
Thanks
Can you share here the cards used in the first 30 battle(s)/war(s)? I’ll compare my results with yours.
Hello ! Thank you so much !
here are the logs:
How to read:
In a line starting with :“comparing” you have the cards that are compared
counter represents turns, p1, p2 represent the amount of cards that player has at the end of the turn

Hello!
This is where things start to become wrong. Mine is comparing 13 (KD) / 2 (2D) instead of 13 / 14. KD and 2D were involved in an ordinary battle instead of a war, before they are compared in “counter 25”. So, you may check what’s gone wrong much earlier in the simulation (“counter 3” and “counter 8”).
You realy save me.
@StepBack13 Thank you soooo much!! =D I was with the same problem… tried three/four ways to optimize my code (changing between Lists, Queues, Arrays and Strings) without success. After seeing your comment, I realized that I also was using 10 to Jack!! I fixed the values and all the tests passed!! Thank you!!!

Thank you so much for providing me a comparison!
It took me till today to figure things out…and i mean reeeeeeally trying hard.
You know what it was? a battle! in the piece of code I provided earlier
if (comp1.v === comp2.v) {
console.error(`consecutive war ${rCounter}`);
rCounter++;
return war(pp1, pp2, rCounter);
} else {
console.error(
`war winner :${
pp1.v > pp2.v ? 1 : 2
} with counter of consequity ${rCounter}`
);
return { winner: pp1.v > pp2.v ? 1 : 2, times: rCounter };
}
}
pp1 and pp2 are arrays and my mind thought it were selected values in question.
Damn…took me simply to export the 1 game 1 battle + my solution into VS code, establish an fs- stream to log to file and parallel print both arrays… Xd
Thank you for advice again))!
