  • What are deterministic context-free grammars? Can you add a definition? – Yuval Filmus Jun 01 '21 at 06:01
  • Here is the definition from Sipser. A deterministic context-free grammar is a context-free grammar such that every valid string has a forced handle. @Yuval – newbie Jun 01 '21 at 06:10
  • Try to use this definition to show inductively that any word has a unique parse tree. Make sure that you understand what unambiguity means, both informally and formally. Intuitively, the condition of having a forced handle forced the parsing to be possible in a unique way. – Yuval Filmus Jun 01 '21 at 06:12
