给你AC代码
```cpp
#include<bits/stdc++.h>
using namespace std;
int main(){
int n,sum=1;
cin>>n;
for(int i=1;i<=n;i++){
for(int j=1;j<=n;j++){
if(sum<10) cout<<'0'<<sum;
else cout<<sum;
sum++;
}
cout<<endl;
}
cout<<endl;
sum=1;
for(int i=1;i<=n;i++){
int b=n-i;
for(int k=1;k<=b;k++){
cout<<" ";
}
for(int j=1;j<=n-b;j++){
if(sum<10) cout<<'0'<<sum;
else cout<<sum;
sum++;
}
cout<<endl;
}
return 0;
}
```
