原題地址:http://oj.leetcode.com/problems/binary-tree-inorder-traversal/ 題意:二叉樹的中序遍歷。這道題用遞歸比較簡單,考察的是非遞歸實現二叉樹中序遍歷。中序遍歷順序為:左子樹,根,右子樹。如此遞歸下去。 解題思路:假設樹為: 1 / \ ...
方法一,記錄子樹的上界和下界,root的左子樹一定小於root的值,root的右子樹一定大於root的值,然后遞歸左子樹和右子樹 方法二,中序遍歷二叉樹,並記錄前繼節點 ...
從前序中序遍歷來重構二叉樹 經典題,從期末考試到考研什么的應該都有 前序遍歷第一個肯定是root 在inorder里面去找root 左邊的是leftsubtree , 右邊的是rightsubtree 然后preorder除去order,后面lifetsubtree.size ...
