Challenge 2: Balance Parenthesis

Given an array containing opening and closing brackets, check whether the brackets are balanced in the array.

We'll cover the following

Problem Statement

Implement a function that takes an array testVariable containing opening ( and closing parenthesis ) and determines whether the brackets in the array are balanced or not. The function also takes startIndex = 0 and currentIndex = 0 as parameters.

What does “Balanced Parenthesis” Mean?

Balanced parentheses mean that each opening bracket ( has a corresponding closing bracket ). Also, the pairs of parentheses are properly nested.

Consider the following correctly balanced parentheses:

()

(())

(())()

((()))((()))

Now have a look at some incorrectly balanced parentheses:

(

)()(

((()()()()

((())))((((()

Input

An array testVariable containing opening and closing parentheses.

Output

True if the parentheses in the input array are balanced, False otherwise.

Sample Input

testVariable = ["(", ")", "(", ")"]

Sample Output

True
