Day 2

Oh damn!

This was a classic "increment as I say" puzzle - perfect for the 5am brain! I managed to bag 94th globally for p1, but took too long for p2 (171st)!

For Part 1 there is not too much to say, just splitlining the input, splitting each line, and checking to see what to increment based off the first item. I won't explain this too much - and yes, we all made that mistake of UP +=1, not just you! Similar story for Part 2, just need to be careful about what to increment/multiply - commented lines are for p2. My raw code is above, feel free to look at it compare it to yours :)

I sense the intensity will ramp up in a couple of days, so time to buckle up....
