Resumable Iterator with Multi-Dimensional Support

Resumable Iterator with Multi-Dimensional Support Problem Overview Create an iterator framework that can be paused and later continued by saving and restoring its position. The exercise grows through four stages: specify an abstract contract, implement a resumable iterator over one list, extend it to two-dimensional data, and then support three dimensions. The central concern is preserving enough serializable state to restart at precisely the same location. Part 1: Design…
