AC代码：
```
#include <bits/stdc++.h>
using namespace std;
int main(){
string a,b;
int sum[502],shi=0,c[502],d[502];
cin>>a>>b;
memset(c,0,sizeof(c));
memset(d,0,sizeof(d));
memset(sum,0,sizeof(sum));
int maxn=max(a.length(),b.length());
for (int i=1,o=a.length()-1;o>=0;i++,o--){
c[i]=a[o]-'0';
}
for (int i=1,o=b.length()-1;o>=0;i++,o--){
d[i]=b[o]-'0';
}
for (int i=1;i<=maxn;i++){
sum[i]+=c[i]+d[i];
sum[i+1]=sum[i]/10;
sum[i]%=10;
}
if (sum[maxn+1]) maxn++;
for (int i=maxn;i>=1;i--) cout<<sum[i];
}

高精度建议用string

AC代码
```python
a=int(input())
b=int(input())
print(a+b)
```
太简单了
