Reverse an Integer | Girls Can Code | Java

Reversing an integer with my 11 year old daughter. Basically if we read a number such as 12345 from the keyboard, then how do we build up the reverse number 54321?

A beginner learning to code will approach problems in different way than an advanced coder. They require more explanation, more research and their solution is more simple. They may miss a few corner cases or come up with a sub-optimal solution. No problem at all! I'll accept it :)

0:00 Hello
0:15 How are we building up the reverse?
2:00 Coding time
3:40 ...And we're done. Or are we?
4:15 Debugging
6:21 It works, but why?
7:45 How about negative numbers?
10:20 Goodbye
