Since ACTA has entered into force, Slavko has been spending his time offline, solving crosswords. Having solved almost all that he could get his hands on, he wants to make a few crosswords of his own. However, he is too sloppy for such fine work, so he has asked you to help him generate the crosswords.
You are given two words, and . The word must be output horizontally, and the word
vertically, so that the two words cross (i.e. share exactly one letter). The shared letter must be the first
letter in that is also contained in , more specifically the first occurrence of that letter in each word.
For example, given the words ABBA
and CCBB
, you need to output lines as shown
below:
.C..
.C..
ABBA
.B..
Input Specification

), thus padding all lines to the length of characters.
