Given the following BNF production rules = A | B | C | () | 1. Write down the four tuples (S, V, Σ, P) of the above BNF grammar. 2. Rewrite the BNF to give + precedence over and force + to be right associative. [The question may not make a real world sense, it serves as a practice to "Grammarly" implement precedence and associative rules.] 3. Rewrite the BNF given to add the postfixes ++ and -- unary operators 4. Use the BNF given, 1) perform a leftmost derivation for each of the following statements: a. A = A * (C+ (B* A)) b. BC (A* B + C) 2) show a parse tree (with leftmost derivation) of the following statement.

I need help with #4 (Please solve both parts). ALSO (if you could), could you maybe help me solve #2 and 3? PLEASE DO #4 FIRST

Given the following BNF production rules
→
<assign>
<id> = <expr>
<id> → A | B | C
<expr> → <expr> + <term> | <term>
<term> → <term> * <factor> | <factor>
<factor> → ( <expr> ) | <id>
1. Write down the four tuples (S, V, E, P) of the above BNF grammar.
2. Rewrite the BNF to give + precedence over * and force + to be right associative.
[The question may not make a real world sense, it serves as a practice to "Grammarly"
implement precedence and associative rules.]
3. Rewrite the BNF given to add the postfixes ++ and unary operators
4. Use the BNF given,
1) perform a leftmost derivation for each of the following statements:
a. A = A *
(C+ (B* A))
b. B = C *
(A * B + C)
2) show a parse tree (with leftmost derivation) of the following statement. (You may attach
a screenshot of your drawing, or use sketchpad app or any other software to draw the
diagram.)
c. A = A * (B + (C))
