Sortable Software Versions

Hard ⏱ 18 min 38% acceptance ★★★★★ 4.8

Implement Version(major, minor, patch) with __eq__ and __lt__ comparing the three numbers lexicographically, decorated with functools.total_ordering so <=, >, >= come free. A list of Versions must sort correctly with plain sorted().

Examples

Output

True

Explanation

Numeric tuple comparison: 10 beats 9 in the minor slot.

Constraints

Use @total_ordering.
Define only __eq__ and __lt__ yourself.
