职工信息管理系统数据结构链表代码生成

职工信息管理系统可以使用链表作为其数据结构之一来存储员工信息。链表是一种线性的数据结构，每个节点包含数据（比如员工姓名、职位等）以及指向下一个节点的指针。下面是一个简单的Python伪代码示例，展示如何创建一个基本的职工信息链表：

# 定义链表节点类
class EmployeeNode:
    def __init__(self, employee_id, name, position):
        self.employee_id = employee_id
        self.name = name
        self.position = position
        self.next = None

# 定义链表类
class EmployeeList:
    def __init__(self):
        self.head = None

    # 添加员工节点
    def add_employee(self, employee):
        new_node = EmployeeNode(employee.id, employee.name, employee.position)
        if not self.head:
            self.head = new_node
        else:
            current = self.head
            while current.next:
                current = current.next
            current.next = new_node

    # 查找员工
    def find_employee(self, id):
        current = self.head
        while current:
            if current.employee_id == id:
                return current
            current = current.next
        return None

    # 删除员工
    def delete_employee(self, id):
        if not self.head:
            return
        if self.head.employee_id == id:
            self.head = self.head.next
            return
        prev = self.head
        current = self.head.next
        while current:
            if current.employee_id == id:
                prev.next = current.next
                break
            prev = current
            current = current.next

# 示例使用
employee1 = Employee("001", "张三", "经理")
employee_list = EmployeeList()
employee_list.add_employee(employee1)  # 添加员工到链表
