以下是使用Java语言完成循环双链表深拷贝的示例代码:
”`java
public class CirDoublyList
private DoubleNode<T> head; // 头节点
public CirDoublyList() {
this.head = new DoubleNode<>();
this.head.prev = this.head;
this.head.next = this.head;
}
public CirDoublyList(CirDoublyList<T> list) {
if (list.isEmpty()) {
return;
}
// 创建新的头节点
this.head = new DoubleNode<>();
this.head.prev = this.head;
this.head.next = this.head;
// 深拷贝所有节点
DoubleNode<T> p = list.head.next;
while (p != list.head) {
insert(p.data);
p = p.next;
}
}
public boolean isEmpty() {
return head.next == head;
}
public DoubleNode<T> insert(int i, T x) {
