Modify the grammar below to add rules for subtraction ( – ), division ( / ), bitwiseor ( | ) and bitwise-and ( & ). the bitwise operations have the same precedence and are the lowest precedence operators. subtraction is the same precedence as addition, and division is the same precedence as multiplication. you may want to put quotes around the "|" for the bitwise-or to distinguish it from the normal alternation symbol.
