COMPILER DESIGN

Detailed explanation-1: -Given grammar is Ambiguous, that is the reason that it is not suitable for predictive parsing.

Detailed explanation-2: -Predictive Parsing To accomplish its tasks, the predictive parser uses a look-ahead pointer, which points to the next input symbols. To make the parser back-tracking free, the predictive parser puts some constraints on the grammar and accepts only a class of grammar known as LL(k) grammar.

Detailed explanation-3: -Predictive Parser is also another method that implements the technique of Top-Down parsing without Backtracking. A predictive parser is an effective technique of executing recursive-descent parsing by managing the stack of activation records, particularly.
