* 1 implement the corresponding requirement: the double chromosphere results generated
The double chromosphere have 2 number in the ball, the front is a red ball, a total of 33, requires 6 not repeat results randomly generated; Followed by a blue ball, blue ball is 16, randomly generated 1
Generate the corresponding results in accordance with the requirements, and the red ball order by size and output overall results (requirements: if the number is less than 10, the front of the output to fill 0)
Output (example: the red ball: 02 07 11 22 25 blue ball: 33 09)

Red ball array [33] 1, take out randomly, arrays are removed out number, so that will not repeat

This is another way, I tried

Arraycopy?
