Parenthesis C# Sharp Exercise




Implement a function to check if a sequence of open and closed parentheses is balanced. In other words, check if each open parenthesis corresponds to a closing one and they are correctly nested.

For example:

"(()()(()))" is OK
"(((()" is an ERROR

Example Code

using System;
using System.Collections;
namespace Expression
    class Program
        static void Main(string[] args)
            string expresion = "()()()()()()";
            bool expresionMal = false;

            Stack pila = new Stack();

            for (int i = 0; i < expresion.Length; i++)
                if (expresion[i] == '(')
                else if (expresion[i] == ')')
                    if (pila.Count > 0)
                        expresionMal = true;

            if (expresionMal)
