Hi there. It's James's daughter here again, and my third grade math teacher is up to her old tricks. This time, she's giving us an even number of digits between 0-9, and she wants us to come up with the smallest possible sum of two numbers that are the same length.

For example, if we're given [0 1 2 3], the smallest sum we can get using those numbers by adding two 2-digit numbers together is 33. That's either 10+23 or 13+20. We don't need to know what the two original numbers are, just what their sum is. We also can't start any of our numbers with a zero, because that's cheating.

You guys did a great job with my earlier problems, and even taught my dad a few things about MATLAB! I hope you can help me out with this one as well!
