Suppose you are running on Linux a process p, with these initial uid values: 
        r_uid == 500
        e_uid == 0
        s_uid == 0
write down the values of these uids, after each of the following system calls (that is, you should write 3 values after each call, and 9 values in a total): 
        seteuid(600);
        setuid(500);
        setuid(0);
