<题目链接> 题目大意: 给定数字n,让你将其分成合数相加的形式,问你最多能够将其分成几个合数相加. 解题分析: 因为要将其分成合数相加的个数最多,所以自然是尽可能地将其分成尽可能小的合数相加的形式.通过找规律,我们能够发现,所有的偶数都能够分成4和6这两个合数的组合,而所有的奇数,在减去9这个最小的奇合数后,就会变成偶数,然后就是和普通偶数一样的处理方式. 普通偶数的处理方式就是,看他能够分成几个4,如果该偶数不为4的倍数,那么就是将其中的一个4换成6.总的最大合数个数为:$n/4$ 而奇数…

题目链接:http://codeforces.com/contest/872/problem/C 题意: 给你一个数n,问你最多能将n分解成多少个合数之和.(若不能分解,输出-1) 题解: 若要让合数个数最多,则n必定只由4,6,9组成. n由n/4和n%4两部分组成. 四种情况: (1)n%4 == 0: 全分成4就好了,所以ans = n/4 (2)n%4 == 1: 剩下的1要和两个4组合成一个9. 所以如果n/4 >= 2,ans = n/4 - 1 否则ans = -1 (3)n%4…

最大传输单元(Maximum transmission unit),以太网MTU为1500. 不同网络MTU如下: 如果最大报文数据大小(MSS)超过MTU,则会引起分片操作.   路径MTU: 网路中主机之间的MTU不是一个常数,取决于所选择的路由,而且路径不一定对称(A到B的选路,B到A的选路).ICMP MTU发现方法.   MSS: 标识TCP传往另一段的最大数据长度,建立连接时,双发通告自己允许的MSS(只能出现在SYN报文中). 因为每一次发送报文都会包含IP及TCP首部,所以,发送…
