以下是ABD#G##CD##F###的二叉树的先序遍历、中序遍历、后序遍历和层序遍历的结果:
先序遍历输出:ABDGFCE
中序遍历输出:DGBAECF
后序遍历输出:DGEBFCA
层序遍历输出:ABCDGFE
如果你想要将这个二叉树可视化,可以使用Python中的turtle库来实现。具体步骤如下:
1.安装turtle库:在命令行中输入pip install turtle进行安装。
2.编写Python代码:
```python
import turtle
def draw_tree(root, turtle, x, y, gap):
if not root:
return
turtle.penup()
turtle.goto(x, y)
turtle.pendown()
turtle.write(root.val, align='center', font=('Arial', 12, 'normal'))
draw_tree(root.left, turtle, x - gap, y - 50, gap / 2)
draw_tree(root.right, turtle, x + gap, y - 50, gap / 2)
class TreeNode:
def __init__(self, val=0, left=None, right=None):
self.val = val
self.left = left
self.right = right
root = TreeNode('A')
root.left = TreeNode('B')
root.left.left = TreeNode('D')
root.left.left.right = TreeNode('G')
root.right = TreeNode('C')
root.right.right = TreeNode('E')
root.right.right.left = TreeNode('F')
turtle.speed(0)
draw_tree(root, turtle, 0, 0, 200)
turtle.hideturtle()
turtle.done()
```
3.运行代码,即可在窗口中看到可视化的二叉树。
