本题要求你写个程序把给定的符号打印成沙漏的形状。例如给定17个“*”,要求按下列格式打印
*****
***
*
***
*****
所谓“沙漏形状”,是指每行输出奇数个符号;各行符号中心对齐;相邻两行符号数差2;符号数先从大到小顺序递减到1,再从小到大顺序递增;首尾符号数相等。
给定任意N个符号,不一定能正好组成一个沙漏。要求打印出的沙漏能用掉
尽可能多的符号。

微博上有个自称“大笨钟V”的家伙,每天敲钟催促码农们爱惜身体早点睡觉。不过由于笨钟自己作息也不是很规律,所以敲钟并不定时。一般敲钟的点数是根据敲钟时间而定的,如果正好在某个整点敲,那么“当”数就等于那个整点数;如果过了整点,就敲下一个整点数。另外,虽然一天有24小时,钟却是只在后半天敲1~12下。例如在23:00敲钟,就是“当当当当当当当当当当当”,而到了23:01就会是“当当当当当当当当当当当当”。在午夜00:00到中午12:00期间(端点时间包括在内),笨钟是不敲的。
根据当前时间替大笨钟敲钟。

给定一个带整数键值的单链表L,本题要求你编写程序,删除那些键值的绝对值有重复的结点。即对任意键值K,只有键值或其绝对值等于K的第一个结点可以被保留。同时,所有被删除的结点必须被保存在另外一个链表中。例如:另L为21→-15→-15→-7→15,则你必须输出去重后的链表21→-15→-7、以及被删除的链表-15→15。

大家都知道“堆栈”是一种“先进后出”的线性结构,基本操作有“入栈”(将新元素插入栈顶)和“出栈”(将栈顶元素的值返回并从堆栈中将其删除)。现请你实现一种特殊的堆栈,它多了一种操作叫“查中值”,即返回堆栈中所有元素的中值。对于N个元素,若N是偶数,则中值定义为第N/2个最小元;若N是奇数,则中值定义为第(N+1)/2个最小元。
输入格式:
输入第一行给出正整数N(<= 105)。随后N行,每行给出一个操作指令,为下列3种指令之一:
Push key
Pop
PeekMedian
其中Push表示入栈,key是不超过105的正整数;Pop表示出栈;PeekMedian表示查中值。
输出格式:
对每个入栈指令,将key入栈,并不输出任何信息。对每个出栈或查中值的指令,在一行中打印相应的返回结果。若指令非法,就打印“Invalid”。
题解:建立2个set,一个存小于中位数的部分,一个存大于中位数的部分,可以用S.erase(S.find(x))删除某个特定元素,记得每次操作后平衡2个set的size

迎着一面矩形的大旗一刀斩下,如果你的刀够快的话,这笔直一刀可以切出两块多边形的残片。反过来说,如果有人拿着两块残片来吹牛,说这是自己迎风一刀斩落的,你能检查一下这是不是真的吗?
注意摆在你面前的两个多边形可不一定是端端正正摆好的,它们可能被平移、被旋转(逆时针90度、180度、或270度),或者被(镜像)翻面。
这里假设原始大旗的四边都与坐标轴是平行的。
输入格式:
输入第一行给出一个正整数N(<=20),随后给出N对多边形。每个多边形按下列格式给出:
k x1 y1 … xk yk
其中k(2 < k <= 10)是多边形顶点个数;(xi, yi)(0 <= xi, yi <= 108)是顶点坐标,按照顺时针或逆时针的顺序给出。
注意:题目保证没有多余顶点。即每个多边形的顶点都是不重复的,任意3个相邻顶点不共线。
输出格式:
对每一对多边形,输出”YES”或者”NO”。
分情况讨论
首先枚举旋转,枚举镜像操作,枚举起点,枚举顺/逆时针
在分为4种情况考虑:
2个全等三角形
直角梯形+三角形
2个直角梯形
五边形+三角形
