WebMar 13, 2016 · It is easy to see that for a given derivation tree there is exactly one leftmost and one rightmost derivation, which in a sense also represent the set of the derivations you'd deem "the same". For applications, you are interested in the parse tree as a representation of some underlying structure that has a specific meaning.

WebThus from a parse tree, we can obtain a leftmost or a rightmost derivation, and from an arbitrary derivation, we can obtain a parse tree.
