4. Consider the context-free grammar G= (V, T, (EXPR), P), where:
V= {(EXPR), (TERM), (FACTOR)}E
T= {+, x, (), a};
(EXPR) is the start variable;
P= Set of production rules as follows:
(EXPR) → (EXPR) + (TERM) | (EXPR) - (TERM) | (TERM)
(TERM) → (TERM) × (FACTOR)| (FACTOR)
(FACTOR) → ( (EXPR) ) | a | b
