Given the following CFG and the string 'if x then y else z', derive whether this string is valid and provide the parse tree if applicable. CFG: S -> if E then S else S; E -> x.
💡 Hint: Start from the start symbol S and apply the production rules.
Construct an ambiguous grammar for simple arithmetic expressions without precedence and demonstrate how it could lead to multiple interpretations for the expression '3 + 4 * 5'.
💡 Hint: Map out the different parse trees for the various derivations.
