123…9 door to door (Posted on 2022-10-27) Difficulty: 3 of 5
Consider the sequence of 9 non zero distinct digits arranged in a 3 by 3 grid , like
547
398
162
Clearly there are 9! (=362880) ways to do it.
If we demand that the consecutive numbers are next-door neighbours
( horizontally or vertically) like
167
258
349
then the number is significantly lower, say N.

Find N & provide your reasoning.

do my excel homework | Comment 12 of 27 |
The way to an effective writing model lies through do my excel homework as a radical rethinking of the role, responsibilities, and tools of the staff directly - in the company of those who will lead the changes and direct to achieve a common goal. In modern realities, successful work depends not so much on compliance with formal instructions and academic knowledge, but on the presence of a strategic vision of flexibility in perceiving things and finding solutions to complex problems, openness to changes, and willingness to learn every day to always "be on top".
