The INI file format is a de facto standard for configuration files. INI files are simple text files with a basic structure. They are commonly associated with Microsoft Windows, but are also used on other platforms. Each line in INI-file stands for key-value mapping or defines new section. A key-value line has a format " key=value ",where key — is the name of some property, and value — it's value. It is possible that it will be spaces from the both sides of key and/or value , the spaces should be ignored. A section line has a format " section ". It means that all key-value lines after it define properties of the specified section. Of cause, the following section line changes the current section. A section line may have spaces around any of brackets. Also you should ignore comment lines — the first non-space character of comment line is " ; ". You task is to write the program which will format given INI-file in a special way: first, print key-value lines which do not belong to any section; print all the sections in the lexicographical (alphabetical) order of their names; inside each of two previous items, order key-value lines lexicographically by " key "; if there are more than one key-value lines with the same key inside a single section (or outside any sections), leave only one line (which appears later in the input data); remove all redundant spaces and lines. The first line contains single integer n ( 1 ≤ n ≤ 510 ) — the number of lines in given INI-file. The rest of the input contains a valid INI-file in n lines. Values of section , key and value contain only Latin letters, digits, " . " and/or " - ". Each line has length not exceeding 255 characters and not less than 1 character. The total length of all the lines does’t exceed 10000. Print formatted INI-file.
