题意: 输入一个正整数N(<=100000),和一个链表的头结点地址.接着输入N行,每行包括一个结点的地址,结点存放的值(-1e5~1e5),指向下一个结点的地址.地址由五位包含前导零的正整数组成.以头结点地址开始的这条链表以值排序后得到的链表的长度和头结点,接着以升序按行输出每个结点的地址和值以及指向下一个结点的地址. trick: 题干说的postive N可是数据点4出现了N==0的数据,有些不解如果N==0应该包含的话不应该用nonnegative N吗... 数据点1包含有些结点并非在…

题意:给出N个结点的地址address.数据域data以及指针域next,然后给出链表的首地址,要求把在这个链表上的结点按data值从小到大输出.样例解释:按照输入,这条链表是这样的(结点格式为[address, data, next]):[00001, 0, 22222]→[22222, 1000, 12345]→[12345, -1, 33333]→[33333, 100000, 11111]→[11111,100, -1]按key值排序之后得到:[12345, -1, 00001]→[00…
