题意:有一排n个牛舍,坐标分别为xi,有m头牛,希望尽可能把他们之间分开,求他们之间最近的两头牛之间的距离最大可以拉到多少。这是二分中最大化最小值的题目,英文的题目又最大又最小有的人不易理解。
思路:显然两头最近的牛的距离太大将没有一种方式安置在牛舍中,两头最近的牛距离越小就越能放置在牛舍中,所以用把答案二分出来,每个mi...

在使用MySQL Workbench查询时,如果查询语句或表过于复杂,查询时间过长(一般600s),此时会报Lost Connection错误。
其实,此时所执行的查询语句依然在执行,只是页面显示超时而已。
如果想要修改time out的时间,可在Edit->Preferences->SQL Editor中修改:
从图中可以看出默认时间是600s,把这个值改大一些就行了。...
