摘要: DescriptionFor a positive integer N , the digit-sum of N is defined as the sum of N itself and its digits. When M is the digitsum of N , we call N a generator of M .For example, the digit-sum of 245 is 256 (= 245 + 2 + 4 + 5). Therefore, 245 is a generator of 256.Not surprisingly, some numbers do no 阅读全文

摘要: DescriptionYou know sorting is very important. And this easy problem is:Given you an array with N non-negative integers which are smaller than 10,000,000, you have to sort this array. Sorting means that integer with smaller value presents first.InputThe first line of the input is a positive integer 阅读全文

摘要: DescriptionThere is an objective test result such as ``OOXXOXXOOO". An `O' means a correct answer of a problem and an `X' means a wrong answer. The score of each problem of this test is calculated by itself and its just previous consecutive `O's only when the answer is correct. For 阅读全文

摘要: Description输入一个字符串,统计此字符串中字母(a-z, A-Z)、数字(0-9)、空格(' '),和其它字符的个数,输出四类字符的个数。字符串以回车来结束输入,回车不纳入统计,要求能处理空串。Input输入包含多个测试用例,第一行为一个正整数t,表示测试用例的个数,以下的t行,每行输入一个字符串(长度不超过500),每行以回车结束。Output对于每个测试用例,第一行输出Letter及其个数,第二行输出Number及其个数,第三行输出Space及其个数,第四行输出Other及其个数,使用空格分开。注意:两个测试用例之间用一个空行分开。用ASCII码的特点做,注意A~ 阅读全文

摘要: Description对输入的n个整数进行排序,按照升序输出。1 <= n <= 10000Input每个case第一行输入一个数,n(当n=0时,结束)接下来输入n个整数Output每个case输出一行,这一行是所有数字按照从小到大排序后的结果,数字与数字之间用空格隔开冒泡法:View Code 1 #include<stdio.h> 2 3 void bubbleSort( int array[], int size ); 4 void printArray( const int array[], int size ); 5 6 int main() 7 { 8 i 阅读全文

摘要: Description向量u=(a1, a2, ...., an)和向量v=(b1, b2, ....., bn)为Rn中的两个向量,判断它们是否线性相关。Input输入包括多组测试用例,每组测试用例包括三行。第一行是一个数n(2<=n<=10),表示向量的维数。第二行是向量u的n个元素。第三行是向量v的n个元素。当输入的n为0时结束。Output对于每组测试用例输出一行。如果u和v线性相关,则输出Yes,否则输出No。这道题的测试用例似乎很糟糕,一开始写了N个漏洞多多的程序居然都给AC(包括判定一个含零向量的向量组线性无关,判定一个每项都是另一向量不同倍的向量为线性相关,某一项有 阅读全文

摘要: Description2. 反序输出将一个正整数 n 以相反的顺序输出的递归算法的伪代码(Pseudocode )可以描述如下:If 要输出的整数只有一位Then 输出该整数Else 输出整数的个位数字反向输出除个位以外的全部数字 End请编写一个函数 void printn(int n)实现以上伪代码,注意要用递归的方法,非递归不给分,并编写主函数调用该函数测试实现是否正确。Inputn为一个简单的int的类型数据Output将用户输入的数字反向输出。一次ACvoid printn( int n ){ if ( n / 10 == 0 ) { pr... 阅读全文
