Reverse a linked list from positionmton. Do it in-place and in one-pass. For example: Given1->2->3->4->5->NULL,m= 2 andn= 4, return1->4->3->2->5->NULL. Note: Givenm,nsatisfy the following condition: 1≤m≤n≤ length of list. 解题思路: 指针操作即可,旋转参考Java for L...

Reverse Linked List II 题目大意 翻转指定位置的链表 解题思路 将中间的执行翻转,再将前后接上 代码 迭代 class Solution(object): # 迭代 def reverseBetween(self, head, m, n): """ :type head: ListNode :type m: int :type n: int :rtype: ListNode """ # 例如[1,2,3,4,5] dummy = List...
使用StringBuilder 或者 stringBuffer 的 reverse() 方法。 示例代码: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 // StringBuffer reverseStringBuffer stringBuffer=newStringBuffer();stringBuffer.append("abcdefg");System.out.println(stringBuffer.reverse());// gfedcba// StringBuilder reverseStringBuilde...
字符串相关:操作字符串的类有String、StringBuffer、StringBuilder。String声明的是不可变对象,每次操作生成新对象。StringBuffer线程安全,性能稍低;StringBuilder非线程安全,性能较高,单线程下推荐使用StringBuilder,多线程下用StringBuffer。例如将字符串反转,可使用StringBuilder或StringBuffer的reverse()方法。
