Solution retrospective

A fun app to develop. The most challenging part was utilizing an algorithm that evaluates a string that has a math expression. I ended up using the postfix algorithm to do exactly that. But first, I needed to convert the math expression from infix (5 + 5) to postfix (5 5 +). Postfix strings are perfect for evaluating math expressions using a stack data structure (my leetcode skills finally helped me for once....). And of course, the app is fully responsive and will look great on any device.
