Input 1: A = " ( ()" Output 1: 2 Explanation 1: The longest valid parentheses substring is " ()", which has length = 2. Cannot retrieve contributors at this time. Notifications Fork 21; Star 38. We push the current character to stack if it is a starting bracket. Are you sure you want to create this branch? If this holds then pop the stack and continue the iteration, in the end if the stack is empty, it means all brackets are well . Code definitions. Because they both are 0 means we use all the parentheses. * If X and Y are valid, then X + Y is also valid. Iterate through string and if it is a open bracket then increment the counter by +1. We will upload your approach and solution here by giving you the proper credit so that you can showcase it among your peers. You need to find whether parantheses in A is balanced or not ,if it is balanced then return 1 else return 0. So there are n opening brackets and n closing brackets. A tag already exists with the provided branch name. Explanation 1: All paranthesis are given in the output list. This problem is commonly asked by the interviewers where we have to validate whether the brackets in a given string are balanced on not. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below. Input 2: A = ") () ())" Output 2: 4 Explanation 2: The longest valid parentheses substring is " () ()", which has length = 4. Output Format Return 1 if parantheses in string are balanced else return 0. If the popped character doesn't match with the starting bracket, brackets are not balanced.
