Hello friends how can I solve this

Parentheses are balanced, if all opening parentheses have their corresponding closing parentheses. Given an expression as input, we need to find out whether the parentheses are balanced or not. For example, "(x+y)*(z-2*(6))" is balanced, while "7-(3(2*9))4) (1" is not balanced. The problem can be solved using a stack. Push each opening parenthesis to the stack and pop the last inserted opening parenthesis whenever a closing parenthesis is encountered. If the closing bracket does not correspond to the opening bracket, then stop and say that the brackets are not balanced. Also, after checking all the parentheses, we need to check the stack to be empty -- if it's not empty, then the parentheses are not balanced. Implement the balanced() function to return True if the parentheses in the given expression are balanced, and False if not. Sample Input: (a( ) eee) ) Sample Output: False https://www.sololearn.com/discuss/2556656/?ref=app https://www.sololearn.com/discuss/2801536/?ref=app

It clearly gives the answer for it as well . And if you don't understand what is stack then maybe google about it and come up with some code before we can help . Also why have you mentioned irrelevant questions in description ?
