if I've understood the problem's conditions right, my
program is absolutly right too (I think so). I've check it
by a lot of different tests.

But I am not sure in the following propety of original
words:

"Лach original word has the following property: the sum of
positions where symbols 1 are located is a multiple of
(N+1) or equal to zero".

Is it true ?
Or I must calculate this sum for ALL original words ?
