Advent of Code 2018 day 3 solution in Julia

made and submitted by porterjamesj
This is my solution to day 3 of Advent of Code 2018 (https://adventofcode.com/2018/day/3). I was pretty excited about this code, because it maps very cleanly to how I thought about the problem in my head when I sat down to write it. I think it's a great illustration of how nice it can be to solve problems like this in languages with built-in support for multidimensional arrays!
