My solution: 0: Z 2 1: Z 3 2: J 0 2 -> 4 3: J 1 3 -> 7 4: I 2 5: J 0 2 -> 4 6: J 1 3 -> 7 7: I 2 8: I 3 9: J 1 3 -> 7

My solution:
0: Z 2
1: Z 3
2: J 0 2 -> 4
3: J 1 3 -> 7
4: I 2
5: J 0 2 -> 4
6: J 1 3 -> 7
7: I 2
8: I 3
9: J 1 3 -> 7
Handles the zero case. Only uses 4 cells total.
- elevensies 11y agoInstruction 6 is a nop? if mem. 1 not-equals mem. 3, jump to 7, or else fall thru to 7? I don't think you can depend on jumping in instruction 3, because you don't control the value of mem. 1, it's input. So if mem. 3 = 0, instructions 2 and 3 will always lead to instruction four.
