Tod — Rla Walkthrough
Final battle-tested solution for all seeds:
Execute a specific sequence of operations to transform an initial input (often a string or integer array) into a target output, all while managing a limited number of cycles.
0x20: MOV R3, R5 ; R5 now holds target 10 Now we need R0 to equal R5 after cycle 12. tod rla walkthrough
0x20: ADD R0, R0 ; R0 = 10 (5+5) 0x21: HLT But that takes 2 cycles. Destiny event at cycle 4 (which never occurs if we halt early). However, the problem says 12 cycles allowed , not required. But wait – the puzzle's twist: . The environment expects exactly 12 cycles to elapse, and a validation routine runs at the end. If you halt early, it fails.
Address | Instruction | Comment ------------------------------------------------ 0x20 | CMP R0, R3 ; compare current vs target 0x21 | JZ 0x2C ; if equal, skip to safety 0x22 | ADD R0, R4 ; else increment (R4=1) 0x23 | MOV R0, R2 ; temporary store in R2 0x24 | CMP R0, R3 ; check again 0x25 | JZ 0x2C 0x26 | ADD R0, R4 0x27 | MOV R0, R2 0x28 | CMP R0, R3 0x29 | JZ 0x2C 0x2A | ADD R0, R4 0x2B | MOV R0, R2 0x2C | NOP ; dummy (0x00 opcode) 0x2D | NOP 0x2E | NOP 0x2F | HLT ; cycle 12 ends here Wait – That’s 16 instructions? No – we count cycles. Each instruction takes 1 cycle. We need exactly 12 cycles from start to HLT. The above would run 0x20 to 0x2F = 16 cycles. So we trim NOPs and adjust. Final battle-tested solution for all seeds: Execute a
Classic TOD-RLA solution: . Step 2.5 – The Proven Solution Pattern Initialize:
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. Destiny event at cycle 4 (which never occurs
However, we cannot guarantee R0 reaches exactly 10 from 5 with only doubles if skips occur.
