this is python
c++是:
#include <iostream>
using namespace std;
int main() {
for( int i = 1; i <= 9; i++ )
for( int j = 1; j <= 9; j++ )
for( int k = 1; k <= 9; k++ )
for( int l = 1; l <= 9; l++ )
for( int m = 1; m <= 9; m++ )
for( int n = 1; n <= 9; n++ )
for( int o = 1; o <= 9; o++ )
for( int p = 1; p <= 9; p++ )
cout << i << ' ' << j << ' ' << ' ' << k << ' ' << l << ' ' << m << ' ' << n << ' ' << o << ' ' << p;
return 0;
}
打字打到手麻······还是python好······
