直到N行的乘法表，其中每个Kth行都是K到Kth项的表

给定数字N ，任务是打印N行，其中每^第K行由K到^第K项的乘法表组成。
例子：

Input: N = 3 
Output: 
1 
2 4 
3 6 9 
Explanation: 
In the above series, in every K^th row, multiplication table of K upto K terms is printed.
Input: N = 5 
Output: 
1 
2 4 
3 6 9 
4 8 12 16 
5 10 15 20 25 
 

方法：想法是使用两个for循环来打印乘法表。 “ i”中的外循环用作“ K”的值，而“ j”中的内循环用作每个“ i”的乘法表的项。 “ i”表中的每个项都可以使用公式“ i * j”获得。
下面是上述方法的实现：

C++

// C++ program to print multiplication table
// till N rows where every Kth row
// is the table of K up to Kth term
#include 
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;
}

// till N rows where every Kth row
// is the table of K up to Kth term
 
class GFG {
 
    // Function to print the multiplication table
    // upto K-th term
    public static 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
                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);
    }
}
