最后一个100的不输出，我个大大大蒟蒻

using namespace std;
int a[200010];
int main() {
	int n;
	cin >> n;
	for(int i=1; i<=n; i++) {
		cin >> a[i];
	}
	sort(a+1,a+n+1);
	a[n+1]=-1e9;
	int cishu=1;
	for(int i=2; i<=n; i++) {
		if(a[i]==a[i-1]) {
			cishu++;
		} else {
			cout << a[i-1] << " " << cishu << endl;
			cishu=1;
		}
	}
	return 0;
}
