Following language: L = {a^n b^n c^n d^n , n ≥ 1} ,How it is CSL and not CFL?
My understanding : We can create PDA as follows for every 'a' push operation and on 'b' pop operation and again on 'c' push operation and on seeing 'd' pop operation. please correct me , if i am wrong. I am sorry, if it is not important. Thanks lot :)

Consider the following class definitions in a hypothetical Object Oriented language that supports inheritance and uses dynamic binding. The language should not be assumed to be either Java or C++, though the syntax is similar. Class P { void f(int i) { print(i); } } Class Q subclass of P { void f(int i) { print(2*i); } } Now consider the following program fragment: P x = new Q(); Q y = new Q(); P z = new Q(); x.f(1); ((P)y).f(1); z.f(1); Here ((P)y) denotes a typecast of y to P. The output produced by executing the above program fragment will be (A) 1 2 1 (B) 2 1 1 (C) 2 1 2 (D) 2 2 2
