One doubt though,
Isn't the third line supposed to be

Instead of
3 6 12 9

Answer 2

#include <iostream>
using namespace std;

int main()
{
int input;
cin>>input;

for (int i=1;i<=input;i++)
{
for(int j=1;j<=i;j++)
{
for(int k=1;k<=j;k++)
{
cout << (j*i)*k<< " ";
}
}
cout << endl;
}
return 0;
}

When u input 3
