初始化,生成线性表3 55 2 9 7 32 66,遍历输出线性表并给出表长; 将你学号后三位数值插入到第3个位置,遍历输出线性表并给出表长; 将第5个元素删除,遍历输出线性表, 给出表长和被删除元素。 销毁线性表,显示销毁结果。的代码

首先,我们需要创建一个简单的线性表结构,并实现初始化、插入、删除和遍历操作。这里我会提供一个基于数组实现的伪代码示例,假设我们有一个`Node`类表示节点,以及一个`LinearList`类处理线性表的操作:
```python
class Node:
def __init__(self, data):
self.data = data
self.next = None
class LinearList:
def __init__(self):
self.head = None
self.length = 0
def initialize(self, elements):
self.head = Node(elements[0])
current = self.head
for element in elements[1:]:
current.next = Node(element)
current = current.next
self.length = len(elements)
def display_and_length(self):
current = self.head
print("线性表:", end=" ")
while current:
print(current.data, end=" ")
current = current.next
print()
print("表长:", self.length)
def insert_at_third_position(self, new_data):
if self.length > 0:
third_node = self.head
for _ in range(2):
third_node = third_node.next
third_node.next = Node(new_data)
self.length += 1
def delete_fifth_element(self):
if self.length > 4:
self.head.next = self.head.next.next
self.length -= 1
deleted_data = self.head.next.data
else:
print("第五个元素不存在")
deleted_data = None
def destroy(self):
self.head = None
self.length = 0
print("线性表已销毁")
# 初始化线性表
initial_elements = [3, 55, 2, 9, 7, 32, 66]
ll = LinearList()
ll.initialize(initial_elements)
ll.display_and_length()
# 插入数据到第三个位置
new_number = int(input("请输入插入的新数值: "))
ll.insert_at_third_position(new_number)
ll.display_and_length()
# 删除第五个元素
ll.delete_fifth_element()
if ll.length > 0:
ll.display_and_length()
else:
print("表为空")
# 销毁线性表
ll.destroy()
```
运行上述代码会按照描述完成各个操作,然后显示线性表内容、长度以及销毁后的状态。
