Unverified50% confidenceFactExact time
In two-stack sliding window aggregation, each element is moved from the back stack to the front stack only once in its lifetime, so the total cost of any sequence of consecutive operations is proportional to the number of elements, with each insertion/deletion/query being O(1) amortized.

UnverifiedTwo-stack sliding window aggregation is a stream computing algorithm that uses two stacks to maintain a sliding window, completing element insertion and expiry deletion in O(1) amortised time, and querying the aggregate value within the window in real time.74% similarUnverified尾调用优化可将本可能占用 O(n) 栈空间的递归转化为 O(1) 的常量空间消耗61% similarUnverifiedAfter determining the ordering, HOST recovers the parent set of each node by recursively stripping indirect effects from the total effect between pairs of nodes.60% similarUnverifiedStackful coroutines allocate an independent stack for each asynchronous task and can suspend at any function depth, but have higher memory overhead.59% similarUnverifiedMake's 'Operation' consumes 1 credit per module execution, and control nodes such as routers and filters are also billed separately.57% similar
