a. Show that the language A, defined below, is context-free by designing a CFG to generate it. You should explain the role of each non-terminal in your grammar, and why it generates the strings that you say it does. A={u#v#wu,v,w{0,1},uR is a substring of either v or w} (uRR denotes the reverse of string u)
