Length bucketing reverses equal-length input order · case 04
Length bucketing reverses equal-length input order.
Case contract
Sort sequences by ascending length while preserving original order among equal lengths.
Why this case matters
This deterministic toy packing rule models a common boundary in preparing bounded training sequences.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| equal length stability | [[-4], [4], [1, 2]] | [[4], [-4], [1, 2]] | Failed |
