Spec

Problem

The n-queens Jest test description contains a typo: hae should be have.

Acceptance criteria

• The test description reads naturally: should not have solution for 3 queens.
• No runtime behavior changes are introduced.

Approach

Fix the typo in the n-queens test name only.

Files likely touched

• src/algorithms/uncategorized/n-queens/__test__/nQueens.test.js

Risk / blast radius

Very low. This is a test description string only and does not affect algorithm behavior.

Test plan

• Run the focused n-queens Jest test.
• Run git diff --check.

Work breakdown (TDD)

TODO

• Fix the typo in the n-queens test description.
• Verify the focused n-queens test still passes.
• Run whitespace diff checks.

Visual verification

No screenshots captured (stub or non-UI change).

Blockers / open questions

Test plan

• pnpm lint
• pnpm typecheck
• pnpm test
• pnpm build
• Manual smoke on the affected surface (see screenshots)
