按要求模拟匹配即可

题目难度不大，直接按要求模拟匹配即可。

#include <bits/stdc++.h>
using namespace std;
int main(){
    int a[]={7, 9, 10, 5, 8, 4, 2, 1, 6, 3, 7, 9, 10, 5, 8, 4, 2};
    char checkCodes[] = "10X98765432";
    string idcard;
	cin>>idcard;
    if (idcard.length()!=18){
        cout<<"No"<<endl;
        return 0;
    }
    
	int total = 0;
    for (int i = 0; i < 17; i++) {
        int digit = idcard[i] - '0';
        int weight = a[i];
        total += digit * weight;
    }

    int checkCodeIndex = total % 11;
    if (idcard[17] == checkCodes[checkCodeIndex]) {
        cout<<"Yes"<<endl;
        return 0;
    } else {
        cout<<"No"<<endl;
        return 0;
    }
