(d) tw E z, l for some string u over 2., www = uu)- 7. Let be the alphabet(0,1). Denote by L the language (IE . I u = vu for some string u .). Prove or disprove that the language L can be expressed as the concatenation of two "non-trivial" languages L1 and L2 over E: L1{c) and L2 {c) and L = L1L2. 8. For each of the following languages, construct a deterministic finite automaton that acceptes the language. You need to give brief and precise interpretations for the states of the machine
