@PaxDaga To indent, type your attempt in a good text editor (e.g. Programmer's Notepad) first, using tabs or spaces to indent. Any good text editor will automatically maintain indentation for you. After that, copy and paste here but click "fixed font" before "send". Do not use LaTeX because it will not be displayed. Use either ASCII or unicode symbols.
