Petya started to attend programming lessons. On the first lesson his task was to write a simple program. The program was supposed to do the following: in the given string, consisting if uppercase and lowercase Latin letters, it: deletes all the vowels, inserts a character " .

Input The first line represents input string of Petya's program. This string only consists of uppercase and lowercase Latin letters and its length is from  1  to  100 , inclusive. Output Print the resulting string. It is guaranteed that this string is...
