明明的随机数 （C语言代码）

解题思路:





注意事项:





参考代码:

#include<stdio.h>

int main()

{

       int n,a[101],i,j,t,count=0;

       scanf("%d",&n);

       for(i=0;i<n;i++)

              scanf("%d",&a[i]);

       for(i=0;i<n;i++)

              for(j=i+1;j<n;j++)

                     if(a[i]==a[j])

                     {

                            a[j]=0;

                     }

                     for(i=0;i<n-1;i++)

                            for(j=i+1;j<n;j++)

                            {

                                   if(a[i]>a[j])

                                   {

                                          t=a[i];a[i]=a[j];a[j]=t;

                                   }

                            }

                            for(i=0;i<n;i++)

                                   if(a[i]!=0)

                                          count++;

                                   printf("%d\n",count);

                            for(i=0;i<n;i++)

                            {

                                   if(a[i]!=0)

                                   printf("%d ",a[i]);

                            }

                            return 0;
