Problem 701 (View Problem)

"Consider the maximum area of connected cells."

Nowhere is "maximum area" defined.

It's just the literal meaning. The largest possible area of a connected set of (black) cells.

Wouldn't the largest possible area be W x H, i.e. the given square with every square a black square?

I think this entire problem needs to be rewritten, judging by the number of people who are utterly at sea regarding the rules to be followed in writing Roman numerals. For example, after giving the three basic rules in bold , it then discusses subtractive combinations, which immediately violates the...

I think the pin feature is a great tool. Is there a reason users are limited to 10 pinned problems? Does it cost the site in some way to allow users more pins?

Here's some reading stuff:

Thanks, although isn't this considered a slight spoiler?

Another thing: is the 100th fraction supposed to be reduced to lowest terms before summing the numerator? I feel that this should be specified in the problem statement.

It is just there to indicate that the pattern shown in the first numbers continues. It shows what an arbitrary section of the list would look like. Here are some other examples of this notation: {1,3,5,7,...,2k+1,...} {1,2,4,8,...,2^k,...} {1,10,1,20,1,30,1,40,...,1,10k,...} So is the pattern that ...

In the problem statement it lists 2k as one of the components of the continued fraction, but nowhere is it stated what k is. Help?

For those who have solved this problem, I've left some questions in the private thread that I'm hoping someone can answer.

The problem states: "Find the smallest positive integer, x, such that 2x, 3x, 4x, 5x, and 6x, contain the same digits." I'm assuming that x itself also has the same digits as 2x, 3x, 4x, 5x, and 6x, but according to the wording of the problem this need not be the case. I don't see why there cannot e...

This problem statement is so confusing. It's hard to solve a problem when I can't even figure out what is being asked. I suggest the problem statement be heavily edited.

I don't see that the problem statements not clarify that the matrix is given as rows.

Finally got this one after trying to figure out what was wrong when I knew my code was correct. Admins, please add a line of clarification in the problem statement, namely one that specifies that the entries in the attached matrix are given as rows and not columns. This might save many people from f...

In the given text file that contains the matrix, are the entries given as columns or as rows? That is, are the first 80 numbers the first row, the second 80 numbers the second row, ..., or are the first 80 numbers the first column, the second 80 numbers the second column, ...?

I solved this problem, and posed a question that is puzzling me in the thread for this problem. Can someone take a look please?

Why are you assuming that English isn't my first language?

Is it then?

It is. As long as PE allows users to choose any flag to represent their location, no assumptions may be made about a user's nationality.

Hi Junglemath I don't know if you are aware that there have been severe attempts to hack Project Euler. A few years ago PE has been shut down for a few months after such an attack, in order to prevent sensitive user data (especially e-mail adresses in combination with password hashes) to be stolen....

Anyone reading this in 2019 want to check some of my numbers? I spent a ton of time on this and I think my program is computing everything correctly, but I keep getting that ugly red X when I submit my answer.
