I’m working on things related to norm a lot lately and it is time to talk about it. In this post we are going to discuss about a whole family of norm. What is a norm? Mathematically a norm is a tota
Just because of its geometric shape: Here is some intentionally non-rigorous intuition: suppose you have a linear system Ax=b for which you know there exists a sparse solution x∗ , and that

给定一个带整数键值的链表 L,你需要把其中绝对值重复的键值结点删掉。即对每个键值 K,只有第一个绝对值等于 K 的结点被保留。同时,所有被删除的结点须被保存在另一个链表上。例如给定 L 为 21→-15→-15→-7→15,你需要输出去重后的链表 21→-15→-7,还有被删除的链表 -15→15。 输入格式: 输入在第一行给出 L 的第一个结点的地址和一个正整数 N(≤105,为结点总数)。

4.7、L2隧道(eoip): 隧道,就是走捷径,使转发速度更快,L2隧道就是说高层报文在链路层即被转发了,而无需走高层协议栈再转发,比如这里要说的eoip(Ethernet over ip),就是说IP报文在以太网就被转发出去了。 对于eoip,linux内核源码没有其实现,是raisecom根据开源代码实现的,在2.10代码树的rcios/eoip/目录下的eoip.c文件,下图是eoip
