Q: Given a string that has various brackets (e.g. “{“, “(“, “[“, “}”, “)”, “]”) built into it, how would one tell that the string has a balanced number of brackets and in order?

A:  The easiest answer is to use a push / pop algorithm. Push any encountered bracket onto a stack. When the closing bracket is encountered, the matching opening bracket should be on the top of the stack and once the end of the string is hit, there should be nothing left to pop off of the stack.
