The program has a bug, has not found a good solution, interested can leave a message, I send the teacher's code, the implementation of the process is not the same
There would have been a sort of small function, but it was too simple to write,,, to fight bugs, just a bubble sort.

Someone is willing to help me to solve the bug of this program not ...
