如何在数组中实现链表？

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

class ArrayBasedLinkedList:
    def __init__(self):
        self.array = []

    def add(self, value):
        node = ListNode(value)
        self.array.append(node)

    def remove(self, value):
        for i, node in enumerate(self.array):
            if node.value == value:
                del self.array[i]
                break

    def search(self, value):
        for node in self.array:
            if node.value == value:
                return True
        return False

    def traverse(self):
        for node in self.array:
            print(node.value, end=" -> ")
        print("None")

# 使用示例
linked_list = ArrayBasedLinkedList()
linked_list.add(1)
linked_list.add(2)
linked_list.add(3)
linked_list.traverse()
linked_list.remove(2)
linked_list.traverse()
print(linked_list.search(1))
print(linked_list.search(2))
