Web Reference: Jul 11, 2025 · We use recursion to solve the problem. Follow the steps below to solve the problem: Define a function findClosing (char c) which takes a character c representing an opening bracket and returns its corresponding closing bracket. Mar 30, 2023 · By the way: If you use recursion you are using a stack (internally). Check for balanced paranthesis using recursion without stack. The code does not use an explicit stack data structure, but it absolutely uses a stack: the call stack. When you encounter a closing bracket, check if the top of the stack was the opening for it. If yes, pop it from the stack. Otherwise, return false.
