Rilevazione di nomi di file compatibili con l'uomo

introduzione I nomi dei file possono variare enormemente, da semplici blah.txta 303549020150514101638190-MSP0.txt. Il primo è generalmente generato dall'uomo, mentre il secondo è spesso generato automaticamente. Non sarebbe bello avere una semplice funzione per fare ipotesi istruite sull'opportunità o meno di considerare un file "amico degli umani"? Ispirato a un post …

Golf gli pseudoprimi!

Introduzione / Contesto In una recente discussione nella chat crittografica sono stato sfidato a discutere / aiutare con il test di primalità di Fermat e i numeri di Carmichael. Questo test si basa sulla premessa che a^(p-1) mod p==1sarà sempre valida per i numeri primi p, ma non sempre per …

Espandi catene di confronto

A differenza di molti linguaggi, Python valuta a<b<cin quanto sarebbe stato fatto nel campo della matematica, in realtà a confronto i tre numeri, al contrario di confrontare il booleano a<ba c. Il modo corretto di scrivere questo in C (e molti altri) sarebbe a<b && b<c. In questa sfida, il …
