REAMDE 文件都按统一的规范来吧，参照我前面的提交。
我真的很看重仓库/文档的规范性与统一性。

假设它sort排序用的是n的复杂度，下面的while循环也就n，一共2n复杂度，不就是O(n)的关系吗？怎么就乘起来了？没有循环嵌套啊

@KongJHong
老哥做题都不按照要求来的吗>_<？
有小伙伴反馈第 41 题复杂度问题，题目限制 O(n)，你 sort 一下复杂度就到 O(nlogn) 了噢~

In solution/0123.Best Time to Buy and Sell Stock III/README.md:
+输入: [1,2,3,4,5]
+输出: 4
+解释: 在第 1 天（股票价格 = 1）的时候买入，在第 5 天 （股票价格 = 5）的时候卖出, 这笔交易所能获得利润 = 5-1 = 4 。
+ 注意你不能在第 1 天和第 2 天接连购买股票，之后再将它们卖出。
+ 因为这样属于同时参与了多笔交易，你必须在再次购买前出售掉之前的股票。
+```
+示例 3:
+```
+输入: [7,6,4,3,1]
+输出: 0
+解释: 在这个情况下, 没有交易完成, 所以最大利润为 0。
+```

不要把错误的思路也提交上来哈，容易引导别人往错误的方向思考。
