定义一个二叉树,将每个数字及其位置存入二叉树的的叶子结点中,左结点值比父结点小,右结点值比父结点大

好的,我可以帮你解答这个问题。以下是一个Python实现的二叉树类,可以实现你所请求的功能:
```python
class Node:
def __init__(self, val, pos):
self.left = None
self.right = None
self.val = val
self.pos = pos
class BinaryTree:
def __init__(self):
self.root = None
def insert(self, val, pos):
if not self.root:
self.root = Node(val, pos)
else:
self._insert(val, pos, self.root)
def _insert(self, val, pos, cur_node):
if val < cur_node.val:
if not cur_node.left:
cur_node.left = Node(val, pos)
else:
self._insert(val, pos, cur_node.left)
elif val > cur_node.val:
if not cur_node.right:
cur_node.right = Node(val, pos)
else:
self._insert(val, pos, cur_node.right)
else:
raise ValueError("Duplicate value found in the tree!")
def inorder_traversal(self):
if not self.root:
return []
else:
return self._inorder_traversal(self.root)
def _inorder_traversal(self, cur_node):
if not cur_node:
return []
else:
return self._inorder_traversal(cur_node.left) + [(cur_node.val, cur_node.pos)] + self._inorder_traversal(cur_node.right)
```
你可以用以下代码来测试这个二叉树类的功能:
```python
tree = BinaryTree()
tree.insert(5, (1, 2))
tree.insert(3, (2, 3))
tree.insert(7, (3, 4))
tree.insert(1, (4, 5))
tree.insert(4, (5, 6))
tree.insert(6, (6, 7))
tree.insert(8, (7, 8))
print(tree.inorder_traversal())
```
这个程序将会输出以下结果:
```
[(1, (4, 5)), (3, (2, 3)), (4, (5, 6)), (5, (1, 2)), (6, (6, 7)), (7, (3, 4)), (8, (7, 8))]
```
这个结果表示二叉树中每个叶子结点的值和位置。
