Grammar in computer science
WebIn computer science, an ambiguous grammar is a context-free grammar for which there exists a string that can have more than one leftmost derivation or parse tree. Every non-empty context-free language admits an ambiguous grammar by introducing e.g. a duplicate rule. A language that only admits ambiguous grammars is called an inherently … WebUnit 1 - Computer Hardware, Memory & Storage. Unit 2 - Software & Issues in Computer Science.
