Solution: Parsing a Boolean Expression
Explore how to parse complex nested boolean expressions by leveraging a stack-based approach. Understand the step-by-step evaluation of logical operators such as NOT, AND, and OR within expressions. This lesson equips you to implement efficient parsing algorithms with linear time and space complexity, enhancing your problem-solving skills for coding interviews.
We'll cover the following...
Statement
You are given a string, expression, that represents a boolean expression. The expression can take one of the following forms:
't': Represents the boolean value TRUE.'f': Represents the boolean value FALSE.'!(expr)': Represents a NOT operation applied to a subexpressionexpr. It returns the logical negation ofexpr.'&(expr1, expr2, ..., exprN)': Represents an AND operation over one or more subexpressions. It returns TRUE only if all subexpressions evaluate to TRUE. ...
