常见的想当然
Slicing a ListSlice of a ListSlice returns a sub-slice with elements offset by the sum of both slice start indices.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- Slicing a ListSlice of a ListSlice yields a sub-slice with the correct offset relative to the parent slice.
- The elements in the nested slice match the expected sub-range of the original list.
