The Turing Challenge - a reward for using Julia

The UK has released a new banknote which features Alan Turing.
People on this forum might be interested in the puzzle challenge with GCHQ (UK agency which is the successor to Bletchley Park) have releases on their website


As this is a challenge… if anyone can prove that the Julia language can be used to solve these puzzles I will try my very best to send a bottle of malt whisky as a prize
clearly the simple puzzles will just need some logic
you need to use the Julia language for the majority of the puzzles
code must be presented
only one bottle of whisky
best efforts to get it to you


You’ve given away the first answer!!!

Maybe we should consider an additional prize for anyone who solves the whole thing with only Base Julia + Turing.jl :smiley:
