最后,我们使用return语句返回这两个列表。 调用函数并使用返回的列表 下面是如何调用函数并使用返回的两个列表的示例代码: result1,result2=return_two_lists()# 调用函数并将返回的两个列表赋值给result1和result2print("List 1:",result1)# 打印返回的第一个列表print("List 2:",result2)# 打印返回的第二...

elif l1.val<l2.val:l1.next=self.mergeTwoLists(l1.next,l2)returnl1else:l2.next=self.mergeTwoLists(l1,l2.next)returnl2 值得注意的是,这里的mergeTwolists函数在类中,调用的话需要在前面加上self。可以代码看出来递归写起来形式非常简单。
