Entries about female citizens contain next to their last maiden name, their last marital name. Your job is to process this information such that all the members of the same family appear together on the same line in an output file called out.txt. Each line in the output file starts with the family last name followed by its members first names e.g. Khaled: Walid, Bernard Kazanjian: Sako, Charbel The most reliable indicators that you can use to figure out the members of the same family are the city of registration and the register number. Some lines contain erroneous information i.e. although a member has the same registration city and registration number as other members of the same family, yet, by mistake his/her last name does not match that of the other members e.g. Najib Mansours last name must have been Khaled. Save all erroneous entries (i.e. copy the whole line from file) to another output file named errors.txt.
