he expressions of the grammar in Fig have two levels of precedence

The expressions of the grammar in Fig. 11.22 have two levels of precedence; + and − at one level, and ∗ and / at a second, higher level. In general, we can handle expressions with k levels of precedence by using k + 1 syntactic categories. Modify the grammar of Fig. 11.22 to include the exponentiation operator ^, which is at a level of precedence higher than * and /. As a hint, define a primary to be an operand or a parenthesized expression, and redefine a factor to be one or more primaries connected by the exponentiation operator. Note that exponentiation groups from the right, not the left, and 2^3^4 means 2^(3^4), rather than (2^3)^4. How do we force grouping from the right among primaries?
