// Function to demonstrate printing pattern
public static void printStars(int n)
{
int i, j;
// outer loop to handle number of rows
// n in this case

// inner loop to handle number of columns
// values changing acc. to outer loop
for(j=0; j<=i; j++)
{
// printing stars

// ending line after each row
