Since finishing up more slowly, if you like java or python people want the code, please private letter I leave a message or comment area.
This is the last semester freshman code written relatively immature, if you want to see which analyze a topic or will not do, can private letter I, or comment will do, if painted zzulioj think the code below useful, like a point look at the pictures.
These are the most basic questions, the questions will not do in this oj, finishing reason is because you want to help people in need, while recording at his own immaturity.
If there is a missing topic, private letter or comment. I will be back.
