Advent of Code is an advent calendar for programming puzzles. I decided to tackle this year’s set of 50 puzzles in Julia and journal my experiences along the way. I’m a beginner in Julia so I thought this would help me improve my skills. This post covers days 9 through 16. Day 9: Bracket matching Syntax error in navigation subsystem on line: all of them I over-engineered the heck out of this puzzle.
