If I want to type name "de", and both names "dd" and "de" are exist in contacts, how much seconds it will take? Should i wait 1 second after first pressing 'd'-key?

Statement doesn't say anything about waiting, it only says "1 push = 1 second", so i guess only this should be taken into account.

ok, then I could mean both ways of pressing key 'def' three times: "ed" or "de" (if this names are in list)

I think so! I'll have a bit of time in 7 hours, so i'll try to solve this task by then to see if i'm right (but i think, most likely i am)

Hmm, i started to try to implement it just now and that made me wonder...
If we have test data like
53
wwa
wwb
...
wwz
wy
wza
wzb
...
wzz
And say, we want to reach "wy" (or anything after it for that matter), and i wonder what happens...
1) we press 9, then press 9 thrice and reach it, or
2) we press 9, then press 9 twice, and at that point it occurs there's nothing starting with "wx", and the 2nd letter is removed?
Well i guess i'll follow 2) for now, but that feels somewhat suboptimal for real phones if we talk about it...

Edit: alright, nevermind... seems i was wrong, should've looked into neighbouring topics initially. Gotta redo it...
