Question

using scanner class write a computer program to print the following pattern:
1
2 6
3 7 10
4 8 11 13
5 9 12 14 15
​

Answer 1

Explanation:

import java.io.*;

// Java code to demonstrate star pattern

public class GeeksForGeeks

{

// Function to demonstrate printing pattern

public static void printNums(int n)

{

// initialising starting number

int i, j, num=1;

// outer loop to handle number of rows

// n in this case

for(i=0; i<n; i++)

{

// without re assigning num

// num = 1;

for(j=0; j<=i; j++)

{

// printing num with a space

System.out.print(num+ " ");

// incrementing num at each column

num = num + 1;

}

// ending line after each row

System.out.println();

}

}

// Driver Function

public static void main(String args[])

{

int n = 5;

printNums(n);

}

}
