Balanced Parentheses Using Stacks
The logic that you used to solve the parenthesis problem using stacks is given below. String is the argument string that is passed into the function.
Logic:
Declare a character stack S
Traverse the expression string.
If the current character is push it into the stack.
If the current character is pop it from the stack. If there is no to pop, throw an exception and return 'false'. If pop is called on an empty stack, then it indicates that the string is formed incorrectly.
If the stack is empty at the end, then it indicates that the string is formed correctly and return True
The method has given above returns 'True' if the algorithm if the string of parentheses is balanced; otherwise, it returns 'False'.
When you use this algorithm, what would be the state of the stack at its end if the string is as shown below?
