How could you convert an ambiguous grammar to an unambiguous one?
To convert the given grammar into its corresponding unambiguous grammar, we implement the precedence and associativity constraints.
Can all ambiguous grammar be converted to unambiguous grammar?
A grammar can be unambiguous if the grammar does not contain ambiguity that means if it does not contain more than one leftmost derivation or more than one rightmost derivation or more than one parse tree for the given input string.
How do you remove ambiguity from ambiguous grammar?
We need to build the parse tree for a given input string that belongs to the language produced by the grammar and then decide whether the grammar is ambiguous or unambiguous based on the number of parse trees obtained as discussed above.
Can we remove ambiguity from context free grammar?
The answer is no. It can be proven that there is no algorithm which can even decide whether a particular context-free grammar is ambiguous.
