Operator-precedence parsing method
Operator-precedence parsing is a bottom-up parsing method used in computer science to analyze and process strings of symbols. Here is the false statement about this parsing method:

Statement: It must contain ε-production

Explanation:
- The statement is false because Operator-precedence parsing method does not require the use of ε-productions. ε-productions are productions in a grammar that can derive the empty string ε.
- Operator-precedence parsing is based on the precedence and associativity of operators in a given grammar. It doesn't rely on the presence of ε-productions.
- The method uses a precedence table to determine the order in which operators should be applied when parsing an input string.
- The absence of ε-productions simplifies the parsing process and makes it more efficient.
- Therefore, the false statement is that Operator-precedence parsing method must contain ε-production.
