In general, a string u is defined to be a substring of a string v if v = ruy for some strings a and y, either or both possibly empty. (a) Prove that the substring relation on any set of strings is a partial order. (b) Draw the Hasse diagram for the substring relation on the strings of two or fewer letters over the alphabet {a,b,c}. (c) Draw the Hasse diagram for the same relation on the substrings of the string abbac. Repeat for the string cababa.
