A linked list can be reversed either iteratively or recursively. Could you implement both? 既然问了能否iteratively or recursively, 那就both把. iterative 解法: 总结就是得到下一个节点,更改当前节点指向,将指针往下移动,直到过完整个linkedlist.

We will see how to reverse a linked list in java. LinkedList is a linear data structure where an element is a separate object with a data part and address part.
def reverseList(self, head): """ :type head: ListNode :rtype: ListNode """ dummy = ListNode(None) while head: # 终止条件是head=Null nextnode = head.next # nextnode是head后面的节点 head.next = dummy # dummy.next是Null,所以这样head.next就成为了Null ...
a commercial Java unit testing tool to generate the test cases. The invariants are used to guide the generation of tests to cover behavior that is not exercised by the existing suite, and then the tests that violate the operational abstractions are selected for inspection. In contrast to a ...
