改正一下就更好啦。
我在宝宝出生之前买了 chicco key fit 30 travel system，当时挺得意的,觉得配
套的就perfect。用了几个月，出门看到别的妈妈推Britax B ready，顿时觉得Britax
好太多了,娃娃面向自己，位置高,遮阳棚大，于是决心也给宝宝换一个。我的基本要求
是：宝宝可以面向自己，而且可以坐的比较高，容易调换座位方向尽量避免晒到宝宝。
Contours Options 3 Wheel Stroller：这一款是我找到的reversible stroller里面最
便宜的，只要169，且声称大多数carseat都可以和它配套。
Bumbleride Flyer Reversible handle stroller：reversible handle stroller 里最
便宜，250。但它有一个缺点就是座位不能反过来，如果想面对宝宝，只能用

and older based on the value of their homes. A reverse mortgage does not
need to be repaid until the homeowner sells the property, moves or passes

But the loans that were intended to help retired homeowners maintain their

Why the UWTI Did a Reverse Split
By Nathan Buehler | January 12, 2016
On Sept. 10, 2015, VelocityShares 3x Long Crude Oil ETN (NYSEARCA: UWTI)
performed its first reverse split using the closing indicative value from
Sept. 9, 2015. This was necessary due to the low value per share after
months of crude oil declines and the expenses that come along with a highly
leveraged fund.

可是看了一下chase quick pay的文件：
Can I reverse a payment?
You cannot initiate a reverse on a completed payment from Chase QuickPay.
Simply ask the other person to send you back the money via Chase QuickPay in
order to settle up. If you suspect fraudulent activity and would like to
reverse a payment, please contact customer support.
说是已经completed payment是不能reverse的啊。难道被骗的都是在complete之前被

发帖数: 3946 | 8 来说说我的思路，reverse list不难，但是这个问题是有环怎么办：比如a -> b -> c
->a，假设一开始从a开始reverse整个环，然后访问link list的next又遇到了b，这时
候就不能再reverse一次了。
思路：先reverse有环的，再reverse没环的
round 1，找出所有环，把环中最后一个指向special "NodeEnd"，所以a -> b -> c ->
a变成 a->b->c->nodeEnd。
round 2，从LL头开始遍历所有Node，假设Node开始的random pointer路径包含nodeEnd
，则重新构成一个逆向的环。
round 3，从LL头开始遍历所有Node，假设Node开始的random pointer路径包含NULL，
则reverse这个list |

发帖数: 712 | 15 我以前在板上看到了，记了个思路，但是忘记帖子的地址了，
题目就是reverse一个double还是float number(记不太清了）
比如123.456， 转成 321.654
思路是先把123转成321，然后把0.456扩大成只有整数（也就是456），记录下来小数点
移了几位，然后反转整数456，得到654， 再把小数点移回去成0.654， 和前面得到的
321相加。
我今天按这个思路写了写，发现小数点右移的过程有点问题，因为我不太清楚java到底
怎么存小数的，给的stop condition不对啊，永远meet不了
大家能帮我看看这行怎么不对吗？

six quick run malgamation, no matter how fast we run, it's still very
difficult to do. Even at that time. we did the SQQS timing for the quick

Your explanation just enlightened me, that we should add a reverse pivot

But anyway, we already changed it to four quick run and it worked quite good. |
