State ambiguity and parsing precisely and explain why it matters in 2-3 sentences.

# Ambiguity and Parsing **Ambiguity** occurs when a single input (sentence, expression, or program) can be interpreted in multiple valid ways according to the grammar rules. **Parsing** is the process of analyzing an input string to determine its grammatical structure according to formal rules, typically producing a parse tree or abstract syntax tree. ## Why It Matters Ambiguity matters because it creates uncertainty in how programs or commands should be executed—if a compiler or interpreter can derive multiple parse trees from the same code, it cannot reliably determine the programmer's intent, leading to unpredictable behavior or compilation errors. For example, the expression `a + b * c` could mean either `(a + b) * c` or `a + (b * c)`, yielding different results; programming languages must establish precedence rules or enforce unambiguous grammars to ensure consistent, deterministic interpretation of all valid programs.
