为什么总超时
[code]
#include "iostream.h"
int main()
{
 int n;
 cin>>n;
 for(int i=1;i<=n;i++)
 {
  int j,a,b=1;
  cin>>a;
  if(a%2==0)
  {
    for(j=2;j<=a/2;j+2)
    {
      if(a%j==0)
       b+=j;
    }
  }
  else
  {
   for(j=3;j<=a/2;j+2)
   {
    if(a%j==0)
      b+=j;
   }
  }
  cout<<b<<endl;
 }
}
