写实现布尔表达式求值的伪代码

以下是一个简单的伪代码示例,用于实现布尔表达式的求值:
```
function evaluateBooleanExpression(expression):
stack = empty stack
for each token in expression:
if token is an operand:
stack.push(token)
else if token is an operator:
operand2 = stack.pop()
operand1 = stack.pop()
result = performOperation(operand1, operand2, token)
stack.push(result)
return stack.pop()
function performOperation(operand1, operand2, operator):
if operator is AND:
return operand1 AND operand2
else if operator is OR:
return operand1 OR operand2
else if operator is NOT:
return NOT operand1
expression = "A AND B OR C"
result = evaluateBooleanExpression(expression)
print("Result:", result)
```
