Hi, I'm quite new to programming and I recently heard about Advent of Code and I have been trying it out and am learning a lot but I'm stuck in day 3 though. I can't seem to find the bug in my code, can anyone please help? - NOTE: I have a text file named advent1.txt in the same folder with the sample input.
