http://acm.hdu.edu.cn/showproblem.php? pid=1032 这题能够用暴力求解.求出在[ni,nj]之间全部数字产生的最大值. 通过观察能够知道,当nk靠近nj的时候,产生的值越多,于是,我认为能够在暴力的基础上做一些小的变化.降低对ni,nj中值得考查 #include <stdio.h> int main() { int m,n,i,max,count,t,j; while(scanf ("%d %d",&m,&n)!…

这是一道很坑爹的题,一定注意输入的两个数的大小,并且不能简单的交换,因为在最后的输出的时候还需要将原来的数按照原来的顺序和大小,这就是为什么还得开辟两个值得原因 Description Problems 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…

这个问题并计算质数了一下相间隔似的.思想上一致. 注意问题: 1 i 可能 大于或等于j -- 这里上传.小心阅读题意,我没有说这个地方不能保证.需要特殊处理 2 计算过程中可能溢出,的整数大于最大值,需要使用long long 关于效率和时间问题: 1 能够使用数组保存中间结果,这样执行快了.内存消耗大了, 2 能够不使用中间数组. 这样执行肯定比較慢了.可是内存消耗小,一样能够AC的. 全部没有个标准吧.看情况而定.假设须要速度就添加数组,假设省内存就不使用数组吧. 这样的题目一般都使用数组…

更简单的水题,穷举法即可. 需要注意的点: 1.i 和 j的大小关系不确定,即有可能 i>j 2.即使i>j,最后输出的结果也要严格按照输出,亦即如果输入10,1,则对应输出也应为 10 1 20而不是1 10 20 代码如下: /* * File: 1207.h * Author: chrischeng021 <chrischeng021@gmail.com> * * Created on July 9, 2015, 5:07 PM */ #ifndef _1207_H #def…
