编写程序建立一个顺序表 逐个输出顺序表中所有元素的值

编写一个程序来创建并操作顺序表（也称为线性表），可以按照以下步骤进行，这里假设我们用Python为例：

class Node:
    def __init__(self, value):
        self.value = value
        self.next = None

class SequentialList:
    def __init__(self):
        self.head = None

    def add_element(self, value):
        new_node = Node(value)
        if not self.head:
            self.head = new_node
        else:
            current = self.head
            while current.next:
                current = current.next
            current.next = new_node

    def display_elements(self):
        elements = []
        current = self.head
        while current:
            elements.append(current.value)
            current = current.next
        for element in elements:
            print(element)

# 使用示例
sequence_list = SequentialList()
sequence_list.add_element(1)
sequence_list.add_element(2)
sequence_list.add_element(3)
sequence_list.display_elements()
