Removing alignment gaps independently pairs different columns · case 05
Removing alignment gaps independently pairs different columns.
Case contract
For equal-length aligned ACGT- strings, return [matches,compared] considering only columns where neither symbol is a gap.
Why this case matters
An offline abstract sequence-data model; useful for testing representation invariants without biological inference.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| variable displaced | [5, 5] | [0, 0] | Failed |
