Get two strings from user input. Let's call them `a` and `b`. Create a bigger string made of the first char of `a`, the first char of `b`, the second char of `a`, the second char of `b`, and so on. Any leftover chars go at the end of the result.

This exercise was taken from [codingbat.com](https://codingbat.com/prob/p125185) and has been adapted for the Python language. There are many great programming exercises there, but the majority are created for Java.
