Day one really got me with those pesky overlapping words like
eightwoortwone.Today was actually really easy the way I did it.
I searched through all the characters of the lines and when I got one that wasn't a number or a period, I looked at all the 8 places around to find the numbers. The numbers I completed by looking in both directions until I got a non-number.
Then I put all numbers and their starting positions in an array, deleted the duplicates and summed them.
By doing this, question 2 only took me 4 minutes.
Yeah it looks like the better solutions generally took that route. I convinced myself that the symbols were going to all have different rules in part 2, so ended up thinking about it way too hard for day 3 ๐
Thought so too, but for me it was a simple match statement (rust), which then became a glorified if statement. ๐
Hmm, I did it the opposite. Found every number and passed a list of every adjacent position of the number to check for non-digit/dot/non-whitespace.
Took a bit longer to solve part 2 due to that approach though.
In that case I was kinda lucky.
But it looked more second-partly to do it that way. ๐
