No! You can't reach "3" from "9" pushing only one key.

Why not?

Because, there is nothing about this kind of actions in the task! From the key "9" you can only reach "1", "8", "6".

You said that we can reach "1" from "9". How? If we push
"Right" we'll reach "a", I think...

Push "Left" and you'll reach "9" from "1"))

I didn't say it. You can reach "3" from "9" by pushing 2 keys!)

1. You said
Because, there is nothing about this kind of actions in the task! From the key "9" you can only reach "1", "8", "6".

So, how we can reach "1" from "9"?

2.Later you said
"Push "Left" and you'll reach "9" from "1"))"
We'll reach "b" by pushing Left.

It's not clear from problem statement because meaning of "moving cursor up" and "moving cursor down" depends on topology. We'd assume default flat topology with boundaries, but special rules for LEFT/RIGHT makes us thinking that there are similar rules for UP/DOWN. At least moving down from row Y-1 to empty cell in row Y could result in stop at the last character.
