This problem concerns languages over the alphabet ? = {1}. For any two integers q,r >0, define the language Lrg over as L1,9 ={1mqtr: m >0}={19,194,129+,...}. For instance, L1,3 ={1,1111,1111111,...}. (a) Show that for every q and r, the language L1,q is regular. (b) Show that if L is a regular language over , then I can be written as L = Lr1,9 UL12,q U...U Lrk,g U Lo, where 0
