首先假设我们实现了将单链表逆序的函数,ListNode reverseListRecursion(ListNode head) ,传入链表头,返回逆序后的链表头。 接着我们确定如何把问题一步一步的化小,我们可以这样想。 把head 结点拿出来,剩下的部分我们调用函数 reverseListRecursion ,这样剩下的部分就逆序了,接着我们把 head 结点放到新链表的尾部就可...

}//这个iterative 的方法要记住 initialize 三个 node. prev, cur, next. 步骤分别是, 保留 next, connect cur and prev,(reverse), 然后移动 prev and cur. 这里看起来没有写断链, 但其实上, 在cur.next = prev 时, 已经断链, 因为每个single linked node 每个node 只有一个next pointer。 把next 指向...
