Draw parse trees for nine strings in question one, using their grammars.

For the following grammars, write the leftmost derivation for the strings given with each. Next to each derivation step, write the number of the rule used. Do not combine steps.
1. grammar (3 rules), Σ = {a, b}:

S -> aSbS | bSaS | ε

strings (3): ab, baab, bbaa

grammar (6 rules), Σ = {0, 1}:

S -> A1B

A -> 0A | ε

B -> 0B | 1B | ε

strings (3): 1, 0011, 01010

grammar (6 rules), Σ = { +, x, a, (, ) }

E -> E + T | T

T -> T x F | F

F -> (E) | a

strings (3): a, a x a, (a) + a x a,

grammar (4 rules), Σ = {(, ), [, ]}:

S -> (S) | [S] | SS | ε

strings (3): ( ), [ ] ( ), ( [ ] )

Draw PDA transition diagram for the following language: The set of strings over the alphabet {x, y} where 2 * (# of x's) = 3 * (#y's) That is, if we let nx be the number of x's and ny be the number of y's, then the strings in these language are those where 2nx = 3ny Try to find a PDA that is as simple and elegant as possible (do not convert from CFG). ------------------------------------------------------------------------------------------------------------------ USE Notation between transition:...
