2.48 Let Σ = {0,1}. Let Ci be the language of all strings that contain a 1 in their middle third. Let C₂ be the language of all strings that contain two is in their middle third. So C₁ {xyz x,ze and y = "1", where |x| = |z|≥ y} and C2 = {xyz|x, z EΣ* and y Є *12*12*, where |x| = |2|≥ |y|}. = a. Show that C₁ is a CFL. b. Show that C2 is not a CFL.
