Balanced Parentheses Checker

You are given a string s consisting of alphabetic characters and parentheses. Your task is to determine if the parentheses in the string are balanced.

A string is said to have balanced parentheses if every opening parenthesis ( has a matching closing parenthesis ) and the pairs are properly nested. For example, the string "(a + b)" has balanced parentheses while "(a + b" does not.

Note: The string may be empty, in which case it is considered balanced.

inputFormat
