给定一个链表,两两交换其中相邻的节点,并返回交换后的链表。 你不能只是单纯的改变节点内部的值,而是需要实际的进行节点交换。 示例: 给定1->2->3->4,你应该返回 2->1->4->3. 注意事项 1、不能简单的交换数值,而是需要更改指针,即确实更改了节点; 2、如果节点个数是奇数,如下图: 那么第5个节点不用...

Swap in C C++ C# Java 写一个函数交换两个变量的值。 C: 错误的实现: voidswap(inti,intj) {intt =i; i=j; j=t; } 因为C语言的函数参数是以值来传递的(pass by value),参数传递时被copy了,所以函数中交换的是复制后的值。 正确的实现:...
