// 边界处理：nums1为空时直接返回空数组（避免后续无效计算）
Option 1: The system can update the cost of that specific shortcut in the base graph and quickly re-run the Dijkstra search (Step 2) on the abstract graph to find an alternative high-level path.。Line官方版本下载对此有专业解读

For implementers, backpressure adds complexity without providing guarantees. The machinery to track queue sizes, compute desiredSize, and invoke pull() at the right times must all be implemented correctly. However, since these signals are advisory, all that work doesn't actually prevent the problems backpressure is supposed to solve.
But we've learned a lot since then. JavaScript has evolved. A streaming API designed today can be simpler, more aligned with the language, and more explicit about the things that matter — like backpressure and multi-consumer behavior.。heLLoword翻译官方下载对此有专业解读
