2. Use the grammar you have created in Question 1 for an infix expression and using the technique: Syntax Directed Definition write appropriate semantic rules to convert an infix expression of that grammar to a prefix expression. Precedence of operators are given below (high to low): • ) Associativity of operators are given below: [Left Associative] [Right Associative] Taking into account the precedence and the associativity of the operators in this question, if any modification is needed for your grammar in Question 1 to be used in this question, do it. After the necessary modification(s), a) write the semantic rules for infix to prefix conversion b) draw the annotated parse tree for the string: a=b/(c-d)*(x+y)
