1. 如果数组长度是n，最多就需要swap n－1次，就是每个元素 最多只需要swap一次。
我们并不需要关心哪个先哪个后swap。 那么 我们就一个一个元素的判断那些需要swap。
2. 首先 如果 给定元素的右边 有更小的值，这个元素就需要swap， 比如上例中的3
3. 然后，再看 剩下的没有swap的元素，如果值比 “在第二步中需要swap的所有元素

A swap agreement created through the synthesis of two swaps differing in

For example, if an investor wants to hedge for a five-year duration

发帖数: 123 | 7 我也是小白。我今天才看了john hull interest swap这一章。 说一点我的看法：
interest rate swap can be recognized as a linear combination of two bonds,
one is long, and another is short.
so the total duration of the bond portfolio and the interest rate swap is
nothing more than the linear combination of three bonds.
When you caculate the weight factor of bond duration you use the present
value of the bond, i.e the market price,
so it make sense to use the market price of the interest swap as the weight
factor, which is jus... 阅读全帖 |

atuma (atuma)：
swap时当前机子和要swap的机子最好都关机或起码在airplane mode下操作。
有版友swap不成功，关机后再操作就搞定。
先复制保存自己的MEID 和ICCID ，再swap 到另外设备（可以是虚拟MEID，需要先用
MEID官网检测确认可用），等二十分钟，再swap 回去即可。
目前swap 仍然免费。虚拟MEID 0630177+四位数字
由于号码从AD 系列转入Mad 系列，涉及号码依托系统的转换，所以出现账户无法呼出
电话。swap大法就是手动触发系统信息重置动作，恢复正常呼叫功能。

有专门的 swap partition 好。你如果用 LVM 的分区
的话也可以动态调整 swap partition。
在文件系统里面做 swap file 有很多不方便和复杂的

Windows 里面的 swap file 也是不能随便移动的。

动态大小可以节省空间，但是我担心会不会导致老是对一小块SSD读写？
2. SWAP分区要多大合适？我内存8G，linux不用起Xserver
感觉SWAP没有windows的page file方便，可以随时改大小，而且也不用在固定的磁盘区
