Consider the following ambiguous context-free grammar. S XaaX | XbbX X+aXbX 1. The grammar above is ambiguous. So, there exist strings that have multiple leftmost derivations in this grammar. However, not all strings are like this. Write down below a length 7 string that has exactly one leftmost derivation in the grammar above. There are many possible correct answers. Choosing any one of them will do
