Discussion @ 1095. Nikifor 3 @ Timus Online Judge

Badd Could anyone explain about "Nikifor knows that a certain positive integer has in its decimal form each of the digits 1,2,3,4" ??? I don't understand it [2] // Problem 1095. Nikifor 3 5 Mar 2002 21:09

I have answers to all your questions :) It means... [1] // Problem 1095. Nikifor 3 5 Mar 2002 22:24

all numbers in the input have at least one '1', one '2', one '3' and
one '4' in their decimal form, is this clear now ? ;)

Thank you for you help.

Now I guess it's the key of this problem. If I can get any of 0~6 by putting 1,2,3,4 as the first 4 digits.
