18217번 - Parentheses Editor 다국어

You are working with a strange text editor for texts consisting only of open and close parentheses. The editor accepts the following three keys as editing commands to modify the text kept in it.

• ‘(’ appends an open parenthesis (‘(’) to the end of the text.
• ‘)’ appends a close parenthesis (‘)’) to the end of the text.
• ‘-’ removes the last character of the text.

A balanced string is one of the following.

• “()”
• “(X)” where X is a balanced string
• “XY ” where both X and Y are balanced strings

Initially, the editor keeps an empty text. You are interested in the number of balanced substrings in the text kept in the editor after each of your key command inputs. Note that, for the same balanced substring occurring twice or more, their occurrences should be counted separately. Also note that, when some balanced substrings are inside a balanced substring, both the inner and outer balanced substrings should be counted.

The input consists of a single test case given in a line containing a number of characters, each of which is a command key to the editor, that is, either ‘(’, ‘)’, or ‘-’. The number of characters does not exceed 200 000. They represent a key input sequence to the editor.

It is guaranteed that no ‘-’ command comes when the text is empty.

Print the numbers of balanced substrings in the text kept in the editor after each of the key command inputs are applied, each in one line. Thus, the number of output lines should be the same as the number of characters in the input line.
