3. How to identify if mathematical language is regular or not? Show differences and similarities. Give examples Illustration 1- All strings of length = 2 over {a, b} * i.e., L= {aa, ab, ba, bb} is regular. If |x| is bounded to certain length, then not regular. Illustration 2 -L= {W x Wr | W, x belongs to {a, b} * and |x|=5} is not regular Identifying mathematical language
