Python 的庫提供了一個 deque object,代表雙端Queue。雙端Queue是 stack 和支持從雙端Queue的任一側向任一方向進行恆定時間插入和刪除的Queue。 下面是一個簡單的例子,展示了在 Python 中使用 deque 來實現Queue數據結構: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25...

At first glance Chronicle Queue can be seen as simplyanother queue implementation. However, it has major design choices that should be emphasised. Usingoff-heap storage, Chronicle Queue provides an environment where applications do not suffer from Garbage Collection (GC). When implementing high-perfor...
A queue can be implanted using stack also. We need two stacks for implementation. The basic idea behind the implementation is to implement the queue operations (enqueue, dequeue) with stack operations (push, pop). Implementation: Let s1 and s2 be the two stacks used for implanting the queue...

Dieser Artikel behandelt die Queuenimplementierung in Python. Eine Queue ist eine lineare Datenstruktur, die der FIFO-Reihenfolge (First-In, First-Out) folgt, dh das zuerst eingefügte Element wird als erstes ausgegeben. Eine Queue unterstützt die folgenden Standardoperationen: enqueue: Fügt...
