Parsing a Boolean Expression
Explore how to parse and evaluate boolean expressions composed of TRUE, FALSE, NOT, AND, and OR operations using stacks. This lesson helps you develop the ability to interpret complex nested boolean expressions and implement their logical evaluation efficiently. You will gain hands-on experience applying stacks to solve a common interview problem that demands careful parsing and boolean logic understanding.
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 ...
