Hi Guys,

I'm not interested in the answer, but I need to be pointed in the right direction

Here's problem 79

I first try to analyze the file myself. I've noticed that the number 7 only ever appears as the first digit.

This immediately implies that all the numbers containing 7 never overlaps with under numbers (on the left side).

Since the questions in project euler always have 1 answer, I believe I'm misunderstanding the question. Do I not have to use all numbers? If I do have to use all numbers, there's many different possible numbers.

Where am I going wrong?

Hi, I've done some Project Euler problems and I was able to solve them very fast because I already knew all the theory behind them. I learned that "accidentaly" because I also had to learn it for university. I used to also solve olympiad problems, I wasn't very good but I was solving some of the problems… >>> More
