Great idea with string multiplication

Mission lacks tests obviously but it It won't work if you have numbers longer than 99 digits in <pre class='brush: python'>ints</pre>. Replacing 99 with <pre class='brush: python'>max(map(log10, ints))</pre> would fix it.

Hi I don't get what exactly "sorted" is doing with that key. May someone explain it please?
