找了好久看不出错哪

#include <bits/stdc++.h>
using namespace std;
int main()
{
	string i;
	cin >> i;
	int x;
	x = i[0] + i[2] * 2 + i[3] * 3 + i[4] * 4 + i[6] * 5 + i[7] * 6 + i[8] * 7 + i[9] * 8 + i[10] * 9;
	x = x % 11;
	if (i[12] == x || i[12] == 'X' && x == 10)
		cout << "Right" << endl;
	else
	{
		for (int l = 0; l <= 11; l++)
			cout << i[l];
		if (x == 10)
			cout << "X" << endl;
		else
			cout << x << endl;
	}
	return 0;
