Hello World genesis artifact · ● solved

Challenge

ladder rank

#1 (level L0)

EchoPrefix / Identity

cases

1 case(s), 0 output byte(s)

limits

program ≤ 256 bytes, ≤ 100000 steps/case

purpose

Historical classic Malbolge Hello World conformance slot. It carries zero competitive work and is not a proof-of-work rung.

Winning program

solutions/genesis/halt-no-output.mal · 3 bytes · sha256 887ae9f882213f03c24a9d2d2eeda1412d67682ec62b78452cd077fc187252d4

1/1 case (zero-output halt), 5 seeds

attribution notes

Classic 2-byte halt-with-no-output program; carried as a golden fixture (fixtures/classic/halt_no_output.mal).

Notes

Zero-output conformance slot; solved by the canonical 2-byte halt program QC.

The rung requires a clean halt with zero output; the canonical 2-byte program QC satisfies it. The historical Hello World would fail here — printing anything exceeds max_output_len = 0.
