Error in problem 2

[olivier-grech]

I believe there's an issue in problem 2.
The answer should be 4613733 and not 4613732.

I think the error comes from the fact that you forgot to add the very first term (1) of the Fibonacci numbers to your sum.

Thanks for the comment Olivier.

It's been years since I wrote these exercises, but I remember tweaking the results so that projecteuler site would accept it.

You are right. Fibonacci starts with either 0, 1 or 1, 1, which both result in the same answer for this question. There is controversy between 0, 1 and 1, 1, but 1, 2 is clearly in the middle of the sequence and wrong. Projecteuler site should also correct their answers.

Feel free to send a pull request :)
