- Create the following hierarchy of files and directories in the home directory of the user 'student', taking into account their permissions:
Europe: drwxr-x---
- Germany: -rwxrwx-wx
- France: -r--r--r--
- Italy: -r-xr-x---
- Spain: -rw--wx--x
- Romania: ----------
- Bulgaria: --wxr-xr-x


- Change the permissions of all files in 'Europe' (recursively) so that all users in the 'student' group have read and write rights on the files.

- Remove all permissions for other users for the files that end with the characters ‘ia’ in the directory ‘Europa’.
