上一篇文章講的是分形之樹(Tree),這一篇中將其簡化一下,來展示二叉分形樹的生長過程。 核心代碼: 軟件截圖: 最后的圖形很像一棵花菜吧。 二叉樹有兩個控制參數,分叉的角度與子樹的長度。通過調節這兩個參數,可以得到不同的圖形 ...
Given a binary tree, return the level order traversal of its nodes' values. (ie, from left to right, level by level). For example:Given binary ...
Given a binary tree, return the bottom-up level order traversal of its nodes' values. (ie, from left to right, level by level from leaf to root ...
Given a binary tree, return the postorder traversal of its nodes' values. For example: Given binary tree {1,#,2,3}, return [3,2,1]. Note ...
Given a binary tree, return the level order traversal of its nodes' values. (ie, from left to right, level by level). For example:Given binary tree ...
Given a binary tree, return the preorder traversal of its nodes' values. Example: Follow up: Recursive solution is trivial, could you do ...
. 這道題要求從中序和后序遍歷的結果來重建原二叉樹,我們知道中序的遍歷順序是左-根-右,后序的順序是左-右- ...
