只有我发题解？👀️ 😕

#include <bits/stdc++.h>
using namespace std;
int sum,isbn[10];
int main(int argc, char **argv){
	char c;int idx = 1,n;
	while (cin >> c){
        n = c - '0';
		if (idx == 10){
			break;
		}
		if (c == '-'){
			continue;
		}
		isbn[idx] = n;
		sum += idx * n;
		idx++;
	}
	cin >> c;	// 可能输入 X, 所以用 c
	n = c - '0';
	if (c == 'X' && sum % 11 == 10){	// 特判正确
		cout << "Right";
	}else if (sum % 11 == n){	// 正常正确
		cout << "Right";
	}else{	// 错误
		cout << isbn[1] << '-';
		for (int i = 2;i <= 4;i++){
			cout << isbn[i];
		}
		cout << '-';
		for (int i = 5;i <= 9;i++){
			cout << isbn[i];
		}
		cout << '-' << sum % 11;	// 别忘了输出的是新的识别码
	}
	return 0;
