There are some pretty good registers(寄存器) in Blitzcrank's body.
There are some instructions about register A and register B:
1．ADD A, B means a += b. The machine code is 80 AF BF.
2．ADD A, A means a += a. The machine code is F0 AF.
3．ADD B, B means b += b. The machine code is F0 BF.
4．ADD B, A means b += a. The machine code is 80 BF AF.
Now give you the values in register A and register B and some machine codes. You should calculate out the final value in register A and register B after operating the machine code.
2 A1 B2 80 AF BF F0 AF B2 B3 F0 AF F0 BF
2A6 B2 164 166
The first case's machine codes 80 AF BF F0 AF is composed of ADD A, B and ADD A, A.
