肆、鏈結串列與二元樹 師大資工系 灆洢 取自於<提升程式設計的邏輯思考力> 6.2 & 6.3
鏈結串列
struct node{ int value; node *next; }; 單向鏈結串列 Singly Linked
List 22 12 32
插入新節點 22 12 32 5 node node.next newnode newnode.next =
node.next; node.next = newnode;
刪除節點 22 12 32 node node.next node.next.next node *delnode =
node.next; node.next = node.next.next; delete delnode;
struct node{ int value; node *prev, *next; }; 雙向鏈結串列 Doubly
Linked List 22 12 32
• List containers are implemented as doubly-linked lists. C++ STL:
list
•127 •101 •133 •10152 •673 •442 作業 •11111 •11234 •540
•10050
二元樹
• 任兩點之間都相通,並且沒有環的圖。 • 來源:演算法筆記 樹 Tree
二元樹 Binary Tree
• 陣列 • 以0為root • 往編號n之左子樹:2*(n+1) - 1 • 往編號n之右子樹:2*(n+1)
• 往父節點:floor((n-1)/2) • 鏈結串列 • struct node { int data; node *left, *right; }; 儲存方式
需要用queue 廣度優先搜尋 BFS: Breadth-first search
深度優先搜尋 DFS: Depth-first search 需要用recursion或stack
樹的走訪:前序、中序、後序
function Preorder(node){ if(!node.left && !node.right){ print(node.value); return; } print(node.value); Preorder(node.left);
Preorder(node.right); } Ans: F,B,A,D,C,E,G,I,H 前序
function Inorder(node){ if(!node.left && !node.right){ print(node.value); return; } Preorder(node.left); print(node.value);
Preorder(node.right); } Ans: ABCDEFGHI 中序
function Postorder(node){ if(!node.left && !node.right){ print(node.value); return; } Preorder(node.left); Preorder(node.right);
print(node.value); } Ans: ACEDBHIGF 後序
• 給予前序與中序,如何找出後序? • 前:DBACEGF 中:ABCDEFG • 後:ACBFGED 問題:二元樹重建
