“1.人生若只如初见，何事秋风悲画扇”

如果人生的很多事，很多的境遇，很多的人，都还如初见时的模样该多好呀！若只是初见，一切美好都不会遗失。很多时候，初见，惊艳；蓦然回首，却已是物是人非，沧海桑田。。。


“2.相濡以沫，不若相忘于江湖”

泉水就要干涸了，为了生存，两条小鱼彼此用嘴里的唾沫来喂养对方，但是，与其这样，还不如在江湖之中畅游，忘记对方的存在。很多时候，我们谴责“大难临头各自飞”，但是从理智的角度来]]>https://blog.youkuaiyun.com/quanquanfly/article/details/6024847https://blog.youkuaiyun.com/quanquanfly/article/details/6024847quanquanflySun, 21 Nov 2010 13:13:00 +0800excel文件：

把画框悬挂在钉子上，总是给人一种很不安全的感觉，如果钉子掉了的话，画框也会重重地砸在地上。像上图那样，把画框挂在两颗钉子上，看上去可就安全得多了——如果有一颗钉子掉了的话，画框仍然能够悬挂在另一颗钉子上，就好像上了双保险一样。
今天，我们要考大家一个完全相反的蛋疼问题——如何把画框挂在两颗钉子上，使得去掉任意一颗钉子，画框都会掉下去？
答案：如下图。这样缠绕绳子后，画框保证能挂稳，但少了任意一颗钉子都不行。你不妨用耳机线和两根手指头亲自试一试。

从表的一端开始，顺序扫描线性表，依次将扫描到的节点关键字和给定值k相比较。
等概率条件下...平均查找长度：ASL = (n+....+2+1)/n= (n+1)/2；
2.二分法查找：
前提是线性表是有序表。假设数据是按升序排序的，对于给定值x，从序列的中间位置开始比较，如果当前位置值等于x，则查找成功；若x小于当前位置值，则在数列的前半段中查找；若x大于当前位置值则在数列的后半段中继续查找，直到找到为止。

      是一种简单的稳定的交换排序，其排序过程为：对于相邻的元素进行大小比较，如果满足排序要求，则不进行交换，否则将两个数进行交换。
      如序列{30, 12, 52, 23, 15, 65, 31, 58, 20,63}：
      以下是第一趟：30跟12比较，30>12交换位置，30<52，不交换位置，以此类推，将序列中最大的数放到最后位置，共执行n - 1次比较。共需要做 n - 1 次起泡。

1.直接插入排序：
      每次从无序表中取出第一个元素，把它插入到有序表的合适位置，使有序表仍然有序。
　　第一趟比较前两个数,然后把第二个数按大小插入到有序表中; 第二趟把第三个数据与前两个数从后向前扫描，把第三个数按大小插入到有序表中；依次进行下去，进行了(n-1)趟扫描以后就完成了整个排序过程，是稳定排序。
      
2.直接选择排序：
