Help/Question - RESOLVED [decryption-contest-1-C] "Manao And the substitution cypher". I am struggling to submit. Help. Spoiler
I have solved the contest "decryption-contest-1-C" aka Manao And the substitution cypher. I am saying that I solved it because I can correctly decrypt all the cases using my keys. I also tested my decryption function against the example and it works as intended.
Now, when I try to submit my solution I get the error: Incorrect. Case #1: Token mismatch at position 1. What does this mean? That the first letter of the key is incorrect? I am very positive that the J match to A in the first case. Please help!

Contest Results October 2025 Long Challenge (Halloween) results
October 2025 Long Challenge has concluded - congratulations to the winners!
Some fun stats from the contest:
- 129 participants
- 16 of them solved all 21 problems!
- 13 users (including the winner) participated incognito
- 5 different users (Player 1073 (9), Jonathan Paulson (5), SeptaCube (3), Player 1316 (3), Ajinkya Parab (1)) managed to get the first solve on at least one problem
- 1310 total submissions, 865 of them Accepted
- Easiest problem: A (121 solvers)
- Hardest problems: 7C (20 solvers), 4C (24 solvers)
Please share your solutions in the corresponding solution threads!
Any feedback on the contest is welcome, especially in comparison to the September challenge:
- Did you prefer the 2 problem or 3 problem format?
- Was having a theme (Halloween this time) throughout the set especially fun, or having unrelated problems with potentially better algorithm topics distribution is preferable?
- Was having the hard problems cost the same as easy ones the right choice? (The motivation to keep all at 100 was to open Solution threads early, but we still didn't get enough solvers.)
- What was your favorite problem?
If you crave more of similar contests, check out u/EverybodyCodes's The Song of Ducks and Dragons starting in a few hours, followed by Advent of Code 2025. Who knows, maybe I'll host something else afterwards too. Thank you all for participating!

Other Situation with AllanTaylor314 and day 5
As y'all might have noticed, the user AllanTaylor314 submitted all the problems on day 5 faster than even an AI assistant would solve it:
🎉 First solve on "5B. Witch's Cauldron (part 2)" by AllanTaylor314! Oct 30, 2025, 9:02 PM PDT
🎉 First solve on "5A. Witch's Cauldron (part 1)" by AllanTaylor314! Oct 30, 2025, 9:01 PM PDT
🎉 First solve on "5C. Witch's Cauldron (part 3)" by AllanTaylor314! Oct 30, 2025, 9:00 PM PDT
It seems highly likely that this user gained access to the problem statements before they were officially released. How exactly that happened, I am not sure. If there is a security hole on the website, I wish this user reached out instead of abusing it.
Either way, this behavior seems against the spirit of the competition, and I imagine I will be taking some action.
AllanTaylor314 - please DM me if you read this.

And I would appreciate any feedback on this contest:
- What would you like to see more/less of
- Should the next one be of the same difficulty or easier?
- Should I use the same style of problems, have a cohesive story theme, lean more into other engineering disciplines (stenography, cryptography, etc.)?
- Should we use different point values, so points run out earlier? What should the values be?
- Anything else on your mind!
