PPT-Precedence and Associativity

Precedence Precedence means how an expression like xRySz Should be evaluated here R and S are different operators If R has the higher precedence than S it will be evaluated as xRy Sz while if S has the higher precedence than R it will be treated as xR. They are also known as BNF or BackusNaur Form Two grammars are equivalent if they generate the same language brPage 2br A derivation in a contextfree grammar can be rep resented by a parse tree the root is the start symbol the interior nodes are non (via .
