Good morning! Here's your coding interview problem for today.

This problem was asked by Facebook.

Given a string consisting of =
parentheses, single digits, and positive and
negative signs, convert the =
string into a mathematical expression to obtain the
answer.

Don't use eval or a similar built-in parser.

For example, given '-1 + (2 +=
 3)', you should return 4.
