Tabla de multiplicar hasta N filas donde cada K-ésima fila es una tabla de K hasta K-ésimo término

Dado un número N , la tarea es imprimir N filas donde cada K ^-ésima fila consiste en la tabla de multiplicar de K hasta K ^-esimo término. 
Ejemplos: 
 

Entrada: N = 3 
Salida: 
1 
2 4 
3 6 9 
Explicación: 
En la serie anterior, en cada ^fila K, se imprime la tabla de multiplicar de K hasta K términos.
Entrada: N = 5 
Salida: 
1 
2 4 
3 6 9 
4 8 12 16 
5 10 15 20 25 
 

Planteamiento: La idea es usar dos bucles for para imprimir la tabla de multiplicar . El ciclo externo en ‘i’ sirve como el valor de ‘K’ y el ciclo interno en ‘j’ sirve como los términos de la tabla de multiplicar de cada ‘i’. Cada término de la tabla de ‘i’ se puede obtener con la fórmula ‘i * j’. 
A continuación se muestra la implementación del enfoque anterior: 
 

// C++ program to print multiplication table
// till N rows where every Kth row
// is the table of K up to Kth term
#include <iostream>
using namespace std;
 
// Function to print the multiplication table
// upto K-th term
void printMultiples(int N)
{
    // For loop to iterate from 1 to N
    // where i serves as the value of K
    for (int i = 1; i <= N; i++)
    {
 
        // Inner loop which at every
        // iteration goes till i
        for (int j = 1; j <= i; j++)
        {
 
            // Printing the table value for i
            cout << (i * j) << " ";
        }
 
        // New line after every row
        cout << endl;
    }
}
 
// Driver code
int main()
{
    int N = 5;
 
    printMultiples(N);
 
    return 0;
}

            // Inner loop which at every
            // iteration goes till i
            for (int j = 1; j <= i; j++) {
 
                // Printing the table value for i
                System.out.print((i * j) + " ");
            }
 
            // New line after every row
            System.out.println();
        }
    }
 
    // Driver code
    public static void main(String args[])
    {
        int N = 5;
 
        printMultiples(N);
    }
}
