@NayutaIto: At breakpoint 2, the memory will be (3,>1), not (3,>0). I don't know why you decremented the second cell. As I explained in my last post, (3,>1) will become (3,3,>0). It will then go

<3,3,0

<2,3,0

2,<3,0

2,2,<2

2,2,2,<1

2,2,2,2,<0

2,2,<1,2

2,2,4,<0

2,<2,4,0

2,<1,4,0

2,1,<4,0

2,1,1,<3,0

2,1,1,1,<2,0

2,1,1,1,1,<1,0

2,1,1,1,1,1,<0,0

2,1,1,1,<1,1,0,0

2,1,1,1,<0,1,0,0

2,1,1,1,2,<0,0,0

2,1,1,<1,2,0,0,0

2,1,<1,4,0,0,0,0

2,<1,8,0,0,0,0,0

<2,16,0,0,0,0,0,0

1,<16,0,0,0,0,0,0

1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,<0

Eventually it will end with <65536.

@WikiaContributor: the - is necessary so that the numbers keep decreasing. The program seems to work fine as is.
