void sort()

{

     int a[]={1,0,0,0,1,1,0,1,0,1,0,0,1,0};

     int i=0;

     int j=13;

     int temp;

      while(j>i)

     {

          if(a[i]==1)

                 i++;

          if(a[j]==0)

                 j--;

          if(a[i]==0)

         {

                 temp=a[i];

                a[i]=a[j];

                a[j]=temp;

         }

     } 

     for(i=0;i<14;i++)

             Console.Write(a[i]+", ");

}

Output: 1,1,1,1,1,1,0,0,0,0,0,0,0
