For a given grammar below, construct an operator precedence relation matrix, assuming *, + are binary operators and id as terminal Symbol and E as non-terminal.

E → E + E $ \ \ \ $ E → E * E $ \ \ \ $ E → id

Apply operator precedence parsing algorithm for the statement

Id - id * id

• Bottom-up parsers for a large class of context-free grammars can be easily developed using operator grammars.
• Operator grammars have the property that no production right side is empty or has two adjacent nonterminal.
• This property enables the implementation of efficient operator-precedence parsers.
• These parser rely on the following three precedence …
