Answer 2

.... Yeap, it's just two different examples. if we write "abc." in input we need take "ab" in output, so delete the last and the previous element. How many "." in line then we delete so many elements in front of it.
These input lines can be anything,for example: "Hello." and in output we should take "Hell".
