不好意思，发错了
```cpp
#include <bits/stdc++.h>
using namespace std;
string w,k;
int a[100005],b[100005],c[1000],n,m,x,s;
signed main(){
cin>>s>>w>>k;
n=w.size();
m=k.size();
for (int i=0;i<w.size();i++){
if (w[w.size()-i-1]>='0'&&w[w.size()-i-1]<='9') a[i+1]=w[w.size()-i-1]-'0';
else a[i+1]=w[w.size()-i-1]-55;
}
for (int i=0;i<k.size();i++){
if (k[k.size()-i-1]>='0'&&k[k.size()-i-1]<='9') b[i+1]=k[k.size()-i-1]-'0';
else b[i+1]=k[k.size()-i-1]-55;
}
if (a[1]==0&&b[1]==0){
cout<<0;
return 0;
}
x=max(n,m)+2;
for (int i=1;i<=x;i++){
c[i]+=a[i]+b[i];
c[i+1]+=c[i]/s;
c[i]%=s;
}
for (int i=1;c[x-i+1]==0&&x>0;x--);
for (int i=x;i>=1;i--){
if (c[i]<10) cout<<c[i];
else{
cout<<char(c[i]+55);
}
}
return 0;
}
