1.
What is the value of MyProc on the following formulas:
(a) q
(b) р^--q
(c) (p^¬¬q) V-p
(d) (q^(pVq)) V (p^¬q)
(e) ((p^(-qVp)) V ((pVq) ^ (p^¬¬q)))
2. State in a brief and precise sentence what My Proc (F) does.
Do not simply "read off" the pseudocode (i.e., "if F is an atom then it
returns 0, ...").

State in a brief and precise sentence what My Proc (F) does. Do not simply "read off" the pseudocode (i.e., "if F is an atom then it returns 0, ...").
Problem 2.
Consider the following recursive procedure applied to
formulas F of the basic syntax (i.e., the only connectives are ^, V,¬):
My Proc (F):
• If F is an atom, then return 0.
• If F is of the form G then return My Proc (G) + 1.
• If F is of the form (GV H) then return max (MyProc(G), MyProc(H)).
• If F is of the from (G^H) then return max(My Proc (G), MyProc(H)).
