Commits

Commit	Rows	What
927faa0	B5, B10, B20, B25	LinkedList.toString → [a,b] (no trailing comma); Vector.toString shows only the stored elements; Statistics.median sorts a copy; Geometry uses Math.PI instead of 3.14. Each has a test that failed first.
c7449a9	N12, N13, N15–N17, N19, N26, N28	API renames: toReversedDigits, digitCount, isRightTriangle, classifyTriangle, SCALENE, getDisplayName, Set → WordSet, fibonacciBinetApproximate. Callers updated.
45e685c	L2, L5, O4, O5, O6, O12, O14	Geometry.sortedSides helper; WordSet looks up a bucket once and stores buckets in an ArrayList; isPositionValid → isInsertablePosition; Arrays.copyOf growth; reuse of next; braces and early returns.
ae95c79	B29, L1, O13	Reader.readLine grows its buffer, so lines over 10,000 bytes work (tested with 20,000); skipWhitespace() replaces 4 copies of the same loop; no chained assignments.
749be58	L3, B27	Public ArrayUtils.swap replaces the boxed-Integer swaps in Insertion and Selection sort and QuickSort's private copy; BinarySearch midpoint is from + (to - from) / 2, with the recursion unchanged.
18ce95e		README layout line.

Visible changes for callers

• The renamed APIs above.
• toString formats of LinkedList and Vector.
• Geometry circle and cylinder results now use the precise π.
• median no longer reorders its input.

Test plan

• ./mvnw clean verify: 616 tests; doclint, Spotless, PMD (it caught one missing final along the way) and coverage floors all pass
• CI, Codacy, Codecov green

Pull Request Overview

👀 Worth a closer look

Reader may corrupt parsing for streams that temporarily return zero bytes without reaching EOF; this should be reviewed before merging. The relevant parsing code has no uncovered-complex-file flag, but targeted regression coverage is still needed for the missing sorting and binary-search scenarios.

Test suggestions

• Verify LinkedList string formatting without a trailing comma, including empty and multi-element lists.
• Verify Vector string formatting includes only stored elements, including an empty vector.
• Verify median returns the correct result without modifying the input array.
• Verify circle and cylinder calculations use precise Math.PI.
• Verify renamed number, geometry, triangle, set, and Fibonacci APIs and their expected results.
• Verify Reader reads lines longer than the initial buffer and continues correctly afterward.
• Verify ArrayUtils.swap exchanges distinct positions and safely handles identical positions.
• Verify all sorting implementations still sort correctly after using the shared swap helper.
• Verify WordSet bucket lookup, duplicate suppression, removal, and empty-word validation.
• Verify BinarySearch behavior for large index ranges where midpoint addition could overflow.

Prompt proposal for missing tests

Consider implementing these tests if applicable:
1. Verify all sorting implementations still sort correctly after using the shared swap helper.
2. Verify BinarySearch behavior for large index ranges where midpoint addition could overflow.

Low confidence findings

• The public API renames appear intentionally breaking; consider documenting a migration path or providing a deprecation/compatibility strategy for existing callers.

_{🟡 MEDIUM RISK}

Suggestion: Consider extracting shared token acquisition or digit-parsing logic from the numeric reader methods so future parser fixes remain consistent across numeric types.
