Tod Rla Walkthrough -

R0=5, R3=10, R4=1, R5=1 (but we never set R5 – oops! we forgot to backup R3). We must add a first instruction to backup R3 into R5. But that uses a cycle.

Classic TOD-RLA solution: . Step 2.5 – The Proven Solution Pattern Initialize: tod rla walkthrough

However, we cannot guarantee R0 reaches exactly 10 from 5 with only doubles if skips occur. R0=5, R3=10, R4=1, R5=1 (but we never set R5 – oops

Example: MOV R5, R0 sets R0 to R5. If it's skipped, R0 stays whatever it was – not good. But ADD R0, R0 twice in a row – if one is skipped, the other still doubles. the solution is trivial:

Also note: R4 = 1 and R5 = 1 . Those might be loop counters. Without randomness, the solution is trivial:
