1001 害死人不偿命的(3n+1)猜想
#include<iostream>#include<stack>using namespace std;int main(){int n,count=0;cin>>n;while(n!=1){if(n%2==0)n=n/2;else n=(3*n+1)/2;count++;}cout<<count;system("pause");return 0;}1002 写出这个数
#include<iostream>#include<stack>using namespace std;int main(){string str;cin>>str;int sum=0;bool start =true;for(int i=0;i<str.length();i++){sum+=(str[i]-'0');}stack<int> sta;while(sum!=0){sta.push(sum%10);sum=sum/10;}while(!sta.empty()){if(start)start=false;else cout<<" ";int tmp=sta.top();sta.pop();switch(tmp){case 0:cout<<"ling";break;case 1:cout<<"yi";break;case 2:cout<<"er";break;case 3:cout<<"san";break;case 4:cout<<"si";break;case 5:cout<<"wu";break;case 6:cout<<"liu";break;case 7:cout<<"qi";break;case 8:cout<<"ba";break;case 9:cout<<"jiu";break;}}system("pause");return 0;}1003 我要通过！
//左边a的个数*中间=右边#include<iostream>using namespace std;int main(){int n;cin>>n;while(n--){string c;cin>>c;int count1=0,count2=0,count3=0,judge=0;bool result=true;for(int i=0;i<c.length();i++){if(c[i]=='P'||c[i]=='A'||c[i]=='T'){if(judge==0&&c[i]=='A')count1++;else if(judge==0&&c[i]=='P')judge=1;else if(judge==1&&c[i]=='A')count2++;else if(judge==1&&c[i]=='T')judge=2;else if(judge==2&&c[i]=='A')count3++;else result=false;}else{result=false;break;}}if(judge!=2||count1*count2!=count3||count2==0)result=false;if(result)cout<<"YES"<<endl;else cout<<"NO"<<endl;}return 0;}1004 成绩排名
#include<iostream>using namespace std;typedef struct student{string name;string num;int score;}Student;int main(){int n;cin>>n;struct student stu[n];for(int i=0;i<n;i++){cin>>stu[i].name;cin>>stu[i].num;cin>>stu[i].score;}struct student min=stu[0];struct student max=stu[0];for(int i=1;i<n;i++){if(stu[i].score>max.score)max=stu[i];if(stu[i].score<min.score)min=stu[i];}cout<<max.name<<" "<<max.num<<endl;cout<<min.name<<" "<<min.num<<endl;return 0;}1005 继续(3n+1)猜想
#include<iostream>using namespace std;int main(){int n;int num[101]={0};cin>>n;for(int i=0;i<n;i++){int tmp;cin>>tmp;num[tmp]=1;}for(int i=0;i<101;i++){if(num[i]==1){int temp=i;while(temp>1){if(temp%2==0)temp/=2;else temp=(3*temp+1)/2;if(temp!=1&&temp<101)num[temp]=0;}}}int flag=1;for(int i=100;i>=0;i--){if(num[i]==1){if(flag==0){cout<<" "<<i;}else{flag=0;cout<<i;}}}return 0;}1006 换个格式输出整数
#include<iostream>using namespace std;int main(){int n;cin>>n;int a,b,c;a=n/100;b=n%100/10;c=n%10;while(a!=0){cout<<"B";a--;}while(b!=0){cout<<"S";b--;}for(int i=0;i<c;i++){cout<<i+1;}return 0;}1007 素数对猜想问题
#include<iostream>#include<vector>#include<math.h>using namespace std;int main(){int n,i,j;cin>>n;int count=0;vector<int> prime;for(int i=2;i<=n;i++){for(j=2;j<=sqrt(i);j++){if(i%j==0)break;}if(j>sqrt(i))prime.push_back(i);}for(int i=1;i<prime.size();i++)if(prime[i]-prime[i-1]==2)count++;cout<<count;return 0;}1008 数组元素循环右移问题
#include<iostream>using namespace std;//change函数void change(int a[],int l,int r){for(int i=l;i<=(l+r)/2;i++){int tmp=a[i];a[i]=a[l+r-i];a[l+r-i]=tmp;}}int main(){int m,n;cin>>m>>n;n%=m;//考虑当需要循环的次数超过了数列总数时的情况！！！int a[m]={0};for(int i=0;i<m;i++){cin>>a[i];}change(a,0,m-1-n);change(a,m-n,m-1);change(a,0,m-1);int count=1;for(int i=0;i<m;i++){if(count==1){cout<<a[i];count=0;}else{count=0;cout<<" "<<a[i];}}}1009 说反话
#include<iostream>using namespace std;int main(){ string str[80]; int i=0,j; while(cin>>str[i]){//这个会经常使用，要记住啊。 i++; } for(j=i-1;j>=0;j--){ if(j!=i-1)cout<<" "; cout<<str[j]; } return 0;}1010 一元多项式求导
#include<iostream>using namespace std;int main(){int a[1000]; int i=0; int m,n; while(cin>>m>>n){ a[i]=m*n; a[i+1]=n-1; if(a[i]==0&&a[i+1]==-1)continue; else i+=2; } for(int j=0;j<i;j++){ if(j!=0){ cout<<" "; } cout<<a[j]; } if(i<1)cout<<"0 0";//注意“零多项式”的指数和系数都是 0，但是表示为0 0. return 0;}1011 A+B 和 C
#include<iostream>using namespace std;int main(){ int n; cin>>n; int i=0; while(n--){ i++; double a,b,c;//看测试用例，选用double或者float类型 cin>>a>>b>>c; if(a+b>c)cout<<"Case #"<<i<<": true"<<endl; else cout<<"Case #"<<i<<": false"<<endl; } return 0;}1012 数字分类
#include<iostream>#include<stdio.h>using namespace std;int main(){ int n,i; cin>>n; int a[1001]; int sum1=0,flag=1,sum2=0,count1=0,count2=0,count3=0,max=0; double sum3=0; for(i=0;i<n;i++){ cin>>a[i]; if(a[i]%2==0&&a[i]%5==0){ sum1+=a[i]; } else if(a[i]%5==1){ sum2=sum2+flag*a[i]; flag=flag*(-1); count2++; } else if(a[i]%5==2){ count1++; } else if(a[i]%5==3){ sum3+=a[i]; count3++; } else if(a[i]%5==4){ if(a[i]>max)max=a[i]; } } if(sum1==0)cout<<"N "; else cout<<sum1<<" "; if(count2==0)cout<<"N "; else cout<<sum2<<" "; if(count1==0)cout<<"N "; else cout<<count1<<" "; if(count3==0)cout<<"N "; else printf("%.1lf ",sum3/count3); if(max==0)cout<<"N"; else cout<<max; return 0;}1013 数素数
#include<iostream>#include<cmath>using namespace std;bool isprime(int n){ int i; if(n==2){ return true; } else if(n<=1){ return false; } else{ for(i=2;i<=sqrt(n);i++){//要用平方根，如果用n/2找素数，会显示一个错误，表示代码运算量过大。 if(n%i==0)return false; } if(i>sqrt(n))return true; else return false; }}int main(){ int m,n; cin>>m>>n; int a[110000]={0}; int x=1; for(int i=1;i<110000;i++){ if(isprime(i)){ a[x]=i; x++; } } int count=0; for(int i=m;i<=n;i++){ count++; count=count%10; if(count==1)cout<<a[i]; else cout<<" "<<a[i]; if(count==0)cout<<endl; } return 0;}1014 福尔摩斯的约会
