Do you like to solve crosswords? If you do, you probably know the traditional lead-in for beginners –
small 3 by 3 crosswords, like the following:
Solve a crossword like this one! Not gonna happen? Fine, then at least put it together given six words
that appear in it (three as horizontal and three as vertical).
Each of the six lines of input contains a word consisting of three uppercase English letters. The words
are given in a lexicographically sorted order.
If it is impossible to put together a 3 by 3 crossword using the given six words, output 0.
Otherwise, output the crossword in three lines.
If there is more than one possible solution, output the one that is first in lexicographic order, where,
for sorting purposes, the crossword is viewed as a nine-letter word obtained by concatenating its rows.
