摘要:一个数组A中存有N(N>0)个整数,在不允许使用另外数组的前提下,将每个整数循环向右移M(M>=0)个位置,即将A中的数据由(A0A1……AN-1)变换为(AN-M …… AN-1 A0 A1……AN-M-1)(最后M个数循环移至最前面的M个位置)。如果需要考虑程序移动数据的次数尽量少,要如何设计移...

摘要:让我们定义 dn 为:dn = pn+1 - pn,其中 pi 是第i个素数。显然有 d1=1 且对于n>1有 dn 是偶数。“素数对猜想”认为“存在无穷多对相邻且差为2的素数”。现给定任意正整数N (#includeusing namespace std;int main(){ int nu...

摘要: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。
输入格式:
输入在一行给...
