也感觉有点烦（禁止抄袭！！！）

#include<bits/stdc++.h>
using namespace std;
int main()
{
    int a,b,c,nd;char d,QW;
    cin>>a>>QW>>b>>QW>>c>>QW>>d;
    int temp=(a*1+b/100*2+b/10%10*3+b%10*4+c/10000*5+c/1000%10*6+c/100%10*7+c/10%10*8+c%10*9)%11;char ntemp;
    if(d!='X') nd=d-'0';
    else nd=10;
    if(temp!=10) ntemp=temp+'0';
    else ntemp='X';
    if(temp==nd) cout<<"Right";
    else cout<<a<<'-'<<b<<'-'<<c<<'-'<<ntemp; 
}

@2044_space_elevator 你礼貌吗

by Andy_Li @ 2023-04-02 20:46:18

@Liumingxuan2010 你这不是讨论区发题解吗？不应该给别人调代码而不是让别人跟你的代码对比吗？举报了讨论区题解

by Indufty_666 @ 2023-04-02 20:48:21

@Andy_Li 我不是帮别人调代码吗

by Andy_Li @ 2023-04-02 20:50:22

@Liumingxuan2010 哪里调了？分明是把AC代码放到这里让别人自己对
