SettingtheNumbers

SettingtheNumbers arranges for each one ten numbers to 1~A freely sequentially and is a number strategic game to face a CPU.

The number of 1~9 is strong so as to be big,
and "A" is the strongest. However, I am poor at 1.
I let a sign fight against the number that I arranged sequentially, and the number of small one becomes extinct if a number is big. In the case of the same number, both numbers become extinct. When one number was exterminated, I win if there is the one where a number is left last.

I find out the strongest sequence, and may you have much victory in your hand?
