We will again make use of the file passwd. Lines in that file take the following format:

<user name>:x:<user id>:<group id>:<full name>:<home directory>:<login shell>
    

Generate a list that contains the ten members of the Faculty of Economics (these have the term fecon in the path of their home directory) that have the smallest group id. If two members have the same group id, members with the largest user id take priority. Write these data to a file, ordered by ascending encrypted user id. In order to do so, encrypt all lines by replacing digits by the corresponding capital at the start of the alphabet. For example, 0 corresponds with A, 1 with B, ... Construct a command that uses as few characters as possible.
