PLEASE ONLY USE EMPTY STACK MODEL OF PUSH DOWN AUTOMATA

Design a PDA with proper comments to accept each of the following languages by empty stack model. NO credit will be given if you design a CFG and then convert it to the equivalent PDA. {a^mb^m | m lessthanorequalto n lessthanorequalto 2m, where m and n greaterthanorequalto 0} {W Element{a, b, C}^* |#_a(w) + #_b(w) = #_c(w)}
