#include <iostream>

using namespace std;

int main()
{
    int input;
    cout << "Enter Value for rows to print: ";
    cin >> input;
    int no = 1;
    int i, j = 0;
    while(i<input)
    {
        while(j<3)
        {
            cout << no << " ";
            no = no + 1;
            j++;
        }
        cout << endl;
        j = 0;
        i++;
    }
    return 0;
