题目描写叙述
学姐在增加集训队之后。学习了使用ubuntu系统来做题,可是没有了360电脑管家,学姐再也没办法看到她的飞速电脑开机究竟虐了全国多少人。作为一个电脑高手。学姐花了几分钟黑到了360的数据库拿到了全国360用户的开机时间,如今学姐想自己算算究竟打败了百分之多少的人?
输入格式
输入有多组数据。
首先给出数据组数T(T≤10),以下T组数据,每组开头为n(1≤n≤100000),360的用户数,和t,学姐的开机时间,接下来n个数字,ti代表第i个用户的开机时间。
当中t,ti为非负整数且小于109。
输出格式
每组数据一行,输出学姐打败了全国百分之多少的用户,精确到小数点后两位。

题目描写叙述
趁着放假。学姐去学车好带学弟去兜风。可是学车真的非常辛苦,每天五点半就要起床赶班车,可是学姐的教练更辛苦,他们要同样的时间到并且日日如此。于是温和的学姐关切的问了他们的歇息情况,教练告诉她。他们两个人倒班教学姐,每一个教练每上n天班就会放一天假,假设一个教练放假,就由还有一个教练来代课。一直代课到自己放假再换人。
如今学姐想知道,每一天是哪个教练给她上课。
输入格式
输入開始为数据组数T(T≤10),接下来T组输入,第一行为n,m,我们如果第一天教学姐的是教练1。并且他教学姐的前一天刚刚放完假。教练2则会在学姐上课的第m天放假,1≤m≤n 以保证每天都有教练教学姐。接下一行为q(q≤103),即询问次数,接着q行,每行ti表示学姐想问哪天的教练是谁。由于教练们很很厉害。并且学姐不知道自己究竟会花多久学完车。你的程序要处理的n。m,ti上限为109。
输出格式
对于每一个询问ti,输出一行。1或2代表当天的教练。

题目描写叙述
学姐正在写作业。可是她写着写着就開始想学弟,走神的她就開始在纸上画圈圈。这时学弟突然出现了,好奇的学弟问学姐在做什么,惊慌之下,学姐随口说想算一下这些圆覆盖的面积为多少。学弟顿时很敬仰学姐。可是学姐突然意识到自己不会做,为了自己能给学弟留下好印象。她来求助你帮她算出来这些圆覆盖的面积。
为了简化问题,我们如果全部圆的半径都为1。
输入格式
输入有多组数据。开头为一个整数T(T≤10),表示数据组数,接下来T组输入,每组开头为一个整数n(1≤n≤100),表示学姐画的圆的个数。接下来n行,每行两个整数xi,yi,表示圆的圆心坐标,1≤xi,yi≤100。
输出格式
输出一个数,表示面积并,精确到小数点后五位。
