For problem 11, can entries be considered row adjacent if they are in a different row. For example, from row 1 to row 2, would entries 91 08 49 49 be considered adjacent?

Please don't make a new topic for a problem if there exists one already.

No. You would have to change directions to get back to 49 49.

Hello,

I was wondering the same. Has an administrator made a comment on any other problems that are the same as this? If so, link?

The reason why I wonder if row to row adjacent is a possibility is because my current algorithm is currently calculating the products as if a number in another row but following a row is adjacent. I personally don't think they are but it made me think and ask this question.

Hello,

Are the ends and beginnings from one row to another considered adjacent? I have read but what I read was vague. Also, I don't really trust anyone except an administrator or someone with many posts.

Example:

20 73 35 29 78 31 90 01 74 31 49 71 48 86 81 16 23 57 05 54
01 70 54 71 83 51 54 69 16 92 33 48 61 43 52 01 89 19 67 48

is 54 and 01 considered adjacent for the problem. To be specific, would "57 05 54 and 01" be adjacent? Initially, I thought no but now I am confused.

No, 57 05 54 01 are not adjacent, because 01 isn't adjacent to 54. (so no scrolling around)
However, 23 57 05 54 or 01 70 54 71 are.

OK,

To me, my question did not meet the criteria for "adjacent" but I wanted to make sure.

Thanks!
