杭电_ACM_Train Problem II
摘要:Problem DescriptionAs we all know the Train Problem I, the boss of the Ignatius Train Station want to know if all the trains come in strict-increasing order, how many orders that all the trains can get out of the railway.InputThe input contains several test cases. Each test cases consists of a numbe

杭电_ACM_Number Sequence
摘要:Problem DescriptionA number sequence is defined as follows:f(1) = 1, f(2) = 1, f(n) = (A * f(n - 1) + B * f(n - 2)) mod 7.Given A, B, and n, you are to calculate the value of f(n).InputThe input consists of multiple test cases. Each test case contains 3 integers A, B and n on a single line (1 <=

杭电_ACM_The 3n + 1 problem
摘要:Problem DescriptionProblems in Computer Science are often classified as belonging to a certain class of problems (e.g., NP, Unsolvable, Recursive). In this problem you will be analyzing a property of an algorithm whose classification is not known for all possible inputs.Consider the following algori

杭电_ACM_Wolf and Rabbit
摘要:Problem DescriptionThere is a hill with n holes around. The holes are signed from 0 to n-1.A rabbit must hide in one of the holes. A wolf searches the rabbit in anticlockwise order. The first hole he get into is the one signed with 0. Then he will get into the hole every m holes. For example, m=2 an

杭电_ACM_汉诺塔VII
摘要:Problem Descriptionn个盘子的汉诺塔问题的最少移动次数是2^n-1,即在移动过程中会产生2^n个系列。由于发生错移产生的系列就增加了,这种错误是放错了柱子,并不会把大盘放到小盘上,即各柱子从下往上的大小仍保持如下关系 :n=m+p+qa1>a2>...>amb1>b2>...>bpc1>c2>...>cqai是A柱上的盘的盘号系列,bi是B柱上的盘的盘号系列, ci是C柱上的盘的盘号系列,最初目标是将A柱上的n个盘子移到C盘. 给出1个系列,判断它是否是在正确的移动中产生的系列.例1:n=3321是正确的例2:n=3312

杭电_ACM_Fibonacci
摘要:Problem Description2007年到来了。经过2006年一年的修炼,数学神童zouyu终于把0到100000000的Fibonacci数列(f[0]=0,f[1]=1;f[i] = f[i-1]+f[i-2](i>=2))的值全部给背了下来。接下来,CodeStar决定要考考他,于是每问他一个数字,他就要把答案说出来,不过有的数字太长了。所以规定超过4位的只要说出前4位就可以了,可是CodeStar自己又记不住。于是他决定编写一个程序来测验zouyu说的是否正确。Input输入若干数字n(0 <= n <= 100000000),每个数字一行。读到文件尾。Out

杭电_ACM_小数化分数2
摘要:Problem DescriptionRay 在数学课上听老师说,任何小数都能表示成分数的形式,他开始了化了起来,很快他就完成了,但他又想到一个问题,如何把一个循环小数化成分数呢?请你写一个程序不但可以将普通小数化成最简分数,也可以把循环小数化成最简分数。Input第一行是一个整数N,表示有多少组数据。每组数据只有一个纯小数,也就是整数部分为0。小数的位数不超过9位,循环部分用()括起来。Output对每一个对应的小数化成最简分数后输出,占一行。Sample Input30.(4)0.50.32(692307)Sample Output4/91/217/52View Code 1 #incl.

杭电_ACM_找新朋友
摘要:Problem Description新年快到了,“猪头帮协会”准备搞一个聚会,已经知道现有会员N人,把会员从1到N编号,其中会长的号码是N号,凡是和会长是老朋友的,那么该会员的号码肯定和N有大于1的公约数,否则都是新朋友,现在会长想知道究竟有几个新朋友?请你编程序帮会长计算出来。Input第一行是测试数据的组数CN(Case number,1<CN<10000),接着有CN行正整数N(1<n<32768),表示会员人数。Output对于每一个N,输出一行新朋友的人数,这样共有CN行输出。Sample Input22560824027Sample Output76801

ACM_七夕节
摘要:Problem Description七夕节那天,月老来到数字王国,他在城门上贴了一张告示,并且和数字王国的人们说:"你们想知道你们的另一半是谁吗?那就按照告示上的方法去找吧!"人们纷纷来到告示前,都想知道谁才是自己的另一半.告示如下:数字N的因子就是所有比N小又能被N整除的所有正整数,如12的因子有1,2,3,4,6.你想知道你的另一半吗?Input输入数据的第一行是一个数字T(1<=T<=500000),它表明测试数据的组数.然后是T组测试数据,每组测试数据只有一个数字N(1<=N<=500000).Output对于每组测试数据,请输出一个代表输
