Giviln the following language: $\{a^n{b}^m{a}^m{b}^n\},$ where $a1.$

Build a context free grammar for this language. Do not use null $()$ production. Show leftmost derivations for two valid strings.

Build a pushdown automata. Trace it with two strings using the stack.

Build a Turing Machine. Trace it with two string using the tape.
