PE Unexpected end of file - int64 expected 晾出代码，希望大佬帮帮忙

#include <bits/stdc++.h>
using namespace std;
int main() {
	freopen("on.in","r",stdin);
	freopen("on.out","w",stdout);
	int n, L, R;
	cin >> n >> L >> R;
	int halfLength = n ;
	int minArea = (halfLength / 2) * (halfLength - halfLength / 2);
	int maxArea = halfLength * (halfLength / 2);
	if (L > maxArea || R < minArea) {
		cout << "-1" << endl;
		return 0;
	}
	int i = halfLength / 2;
	int j = halfLength - i;
	while (true) {
		int area = i * j;
		if (area >= L && area <= R) {
			cout << i << " " << j << endl;
			return 0;
		} else if (area < L) {
			i++;
			j--;
		} else {
