Firstly I was using regex to get if the number of parentheses in a string is balanced or not, but the performance was quite slow when any large string was passed to the regex. The appropriate data structure to solve this problem is Stack.This is one of the important tasks of a compiler. Ask Question Asked 4 years, 1 month ago. You might try, "Paul McGuire"
arr[i], Sliding Window Maximum (Maximum of all subarrays of size k), Sliding Window Maximum (Maximum of all subarrays of size k) using stack in O(n) time, Next greater element in same order as input, Maximum product of indexes of next greater on left and right, Stack | Set 4 (Evaluation of Postfix Expression), Adding new column to existing DataFrame in Pandas, Python program to convert a list to string, How to get column names in Pandas dataframe, Reading and Writing to text files in Python, Iterative Boundary Traversal of Complete Binary tree, isupper(), islower(), lower(), upper() in Python and their applications, Python | Split string into list of characters, Python program to check whether a number is Prime or not, Write Interview
"(1(2)))))"). Since this is such a famous programming problem, the chances are that most of us would have solved this during the CS101 course or somewhere else. Write a Python program to remove the parenthesis area in a string. Approach: Declare a Flag variable which denotes expression is balanced or not. > Okay! By the end of the string, j should equal zero if the parentheses are balanced (every open parenthesis has a matching close parenthesis). I've encountered this while trying to solve an assignment question in the NLP class of Coursera. On Jun 12, 6:06*am, David C. Ullrich
