Warmup problem #2

Warmup problem

It’s happening! Finally December is here again, and a new Advent of Code begins. This year I’m changing it up slightly, and in addition to solving them in Go, I’m solving some if them in TypeScript. To go for the leaderboard or not? The timing for Advent of Code is a bit unfortunate in my time zone, for night owls such as myself. I tried waking up 05:45 every day a few years ago, but this lead to sleep deprivation and “AoC”-burnout.

(Norwegian) I dag lærte jeg: Hvis du ønsker å tilgjengeliggjøre en server som kjører på en mobiltelefon, bak en 4G-ruter, eller på en PC med SIM-kort, og er på Telenor-nettverket (Telenor, Vipps Mobil, Fjordkraft, Gudbrandsdal Energi, Happybytes, NorgesEnergi), kan du gjøre følgende: I nettverksinnstillingene på dingsen din, finn “APN” (Access Point Name). Hos Telenor er denne f.eks. telenor.smart eller telenor.fwa. Endre denne til internet.public, og skru av/på flymodus eller restart dingsen din.

It’s happening! Finally December is here, and a new Advent of Code begins. I’ll try to write a very short post for each of my solutions.
