Explanation:

Predictive parsing is a top-down parsing technique that uses a lookahead symbol to predict which production rule to use to generate the input string. The grammar A AA | (A) | is not suitable for predictive parsing because it is left-recursive.

1. Left-Recursive Grammar:

A grammar is called left-recursive if there is a non-terminal symbol A that can derive a string beginning with itself. In the grammar A AA | (A) |, the non-terminal symbol A can derive a string beginning with itself, which makes it left-recursive.

2. Predictive Parsing:

Predictive parsing is a top-down parsing technique that tries to predict which production rule to use to generate the input string. It uses a lookahead symbol to predict the next input symbol and then uses a set of production rules to generate the input string.

3. Issues with Left-Recursive Grammar:

Left-recursive grammars are not suitable for predictive parsing because they can lead to infinite recursion. When a left-recursive rule is encountered during parsing, the parser will keep expanding the rule until it runs out of memory or exceeds the maximum recursion depth.

4. Solution:

To make the grammar suitable for predictive parsing, we need to eliminate left-recursion. One way to eliminate left-recursion is to rewrite the grammar using right-recursion. Another way is to use a technique called left-factoring, which involves factoring out common prefixes from the production rules.

In conclusion, the grammar A AA | (A) | is not suitable for predictive parsing because it is left-recursive. To make the grammar suitable for predictive parsing, we need to eliminate left-recursion using techniques such as left-factoring or right-recursion.
