在本例中,我們實作雙向連結串列 (doubly-linked list),雖然會多一點點記憶體空間,在從頭端或尾端加入資料時,效率會更好。由於程式碼略長,讀者可到這裡觀看完整程式碼,我們會分段展示部分程式碼。 實作連結串列時,需實作內部節點,這個節點不會暴露在外: local Node = {} Node.__index = Node function Node:...
A Deque can be implemented either using a doubly linked list or circular array. In both implementation, we can implement all operations in O(1) time.
