Description: 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. Input Format: 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. Output Format: Print formatted INI-file. Note: None
