O que costuma-se supor
Calling `mergeSort` with an explicit supertype, such as `mergeSort<num>`, should be treated as a normal typed call even when the argument is a `List<int>`.
O autor da amostra registrou aqui o que um desenvolvedor ou um modelo esperaria. O contrato abaixo é o que de fato rodou.
Contrato
- `mergeSort<num>` on a `List<int>` completes without throwing and sorts the list in place.
- The resulting list is in non-decreasing order, proving the in-place merge sort completed correctly.
