在一些运维场景中,常常需要比较两个环境中的应用目录结构(是否有文件/目录层面上的增删)以及比较两个环境中同名文件内容的不同(即文件层面上的改).Python自带了两个内建模块可以很好地完成这个工作,filecmp和difflib.前者主要用于比较目录结构上的不同以及笼统的文件内容比较:后者用于比较两个文件具体内容上的不同.综合使用两个模块可以比较完备地做一次比较. [filecmp] filecmp提供一些方法可以很方便地进行对比两个目录在结构上的不同以及笼统的文件内容上的异同.比如 filec…

[分析] “虽然不是求什么最大的最小值(或者反过来)什么的……但还是可以用二分的,因为之前就做过一道小数型二分题(下面等会讲) 考虑二分面积,下界L=0,上界R=∑ni=1nπ∗ri2.对于一个中值x和一张半径r的饼来说,这张饼能够分出的最多分数显然是:⌊π∗r2x⌋,所以我们只需要求出∑ni=1⌊π∗ri2x⌋,判断其与f+1的关系即可 特别要注意的一点:π的大小!,因为r≤104r≤104,所以r2≤108r2≤108,又因为题目要求精确到三位小数,所以ππ就要精确到10-11,即π=3.1…
