天平平衡时间限制: 1 Sec  内存限制: 128 MB提交: -  解决: -[提交][状态][讨论版]题目描述天平是一种衡器，是衡量物体质量的仪器。它依据杠杆原理制成，在杠杆的两端各有一小盘，一端放砝码，另一端放要称的物体，杠杆中央装有指针，两端平衡时，两端的质量（重量）相等。现在递归地描述一个天平：1.每个天平用两个正整数代表左右两端的质量。2.如果

这题简单，用个基础摸运算就行#include<stdio.h>#include<stdlib.h>#include<time.h>#include<algorithm>using namespace std;int main() { int n; while(scanf("%d",&n)!=EOF) { int i,j,k=1; fo

根据字典序进行排序，这里用到了sort是c++的用法，以前的代码，有大神指导下才用了sort，这里接触有点早。可以直接按数字把它当成asc码数字处理，所以排数字就行了。#include<stdio.h>#include<stdlib.h>#include<time.h>#include<algorithm>using namespace std;int main() { char

字符串题目了 练好基础，受益良多#include<stdio.h>int main() { int i,j,n,m; while(scanf("%d %d",&i,&j)!=EOF) { printf("+"); for(n=1; n<=i; n++) printf("-"); printf("+\n");

一个if条件句，初学时用#include<stdio.h>#include<math.h>int main() { double a; while(scanf("%lf",&a)!=EOF) { if(a<=100&&a>=90) printf("A\n"); else if(a>=80&&a<=89) pr

公式题#include<stdio.h>#include<math.h>#define PI 3.1415927int main() { double i,j,k,n; while(scanf("%lf %lf %lf %lf",&i,&j,&k,&n)!=EOF) { printf("%.2f\n",pow(pow(k-i,2)+pow(n-j,2),

pow函数都是浮点型参数。你也可以直接列公式#include<stdio.h>#include<math.h>#define PI 3.1415927int main() { double i,j; while(scanf("%lf",&i)!=EOF) { j=PI*pow(i,3)*4/3; printf("%.3f\n",j); }

入门级#include<stdio.h>int main() { double i; while(scanf("%lf",&i)!=EOF) { if(i>=0) printf("%.2f\n",i); else printf("%.2f\n",-i); } return 0;}http:/

博客首发，重在体验#include<stdio.h>int main() { double a,b,c,d; scanf("%lf",&d); for(int i=1;i<=d;i++) { scanf("%lf%lf%lf",&a,&b,&c); if(a+b>c&&a+c>b&&b+c>a&&a-b<c&&a-c<b&&b-c<a

a和c的最大公约数为b，所以a是b的倍数，要求最小的c，一个循环从b+1–a#include<stdio.h>int max(int a,int b) { if(a%b==0) return b; else return max(b,a%b);}int main() { int n; scanf("%d",&n); whi
