int min;
};
Icons::Icons(int n):num(n){
GetMin();
}
void Icons::GetMin(){
int n;
for (int i = 2;; i++){
if (i % 2)
n = i / 2 * (i / 2 + 1);
else
n = i / 2 * (i / 2);
if (n >= num){
min = i;
return;
}
}
}
void Icons::Show(){
int n;
for (int i = 1; i < min; i++){
n = i*(min - i);
if (n >= num){
cout << i << " " << min - i << endl;
}
}
}
int main(){
int n;
cout << "请输入鹅卵石数:\n";
cin >> n;
Icons icons(n);
icons.Show();

}
