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.

essay store | Comment 22 of 27 |
To write an essay, one must start by understanding the topic or prompt, and conduct research if necessary to gather relevant information and ideas. The essay should have a clear structure, including an introduction that presents the thesis statement and provides context for the topic, a well-developed body that presents supporting arguments and evidence, and a conclusion that summarizes the key points and restates the thesis in a meaningful way. You can also use essay store for additional info on how to write essays. It is important to write with clarity, coherence, and precision, using strong and varied vocabulary and correct grammar and punctuation. Additionally, revising and editing the essay carefully can ensure that it is polished and error-free.
