=========
Right side Right angled Triangle.

class LeftRightAngledTriangle{
    public static void main(String[] args)
    {
        // we need to iterate on rows first
        int rows = 5;
        for(int r = 1;r <= rows;++r)
        {
            //printing of spaces
            for(int s = 1;s <= 2*(rows-r);s++)
            {
                System.out.print(" ");
            }
            for(int c = 1;c <= r;c++)
            {
                System.out.print("* ");
            }
            System.out.println();
        }
    }
}

class pyramidPattern{
    public static void main(String[] args)
    {
        int rows = 6;
        // row operation
        for(int r = 0;r < rows ;r++)
        {
            // printing of spaces
            for(int s = (rows - r);s > 1;--s)
            {
                System.out.print(" ");
            }
            // printing 0f *
            for(int c = 0;c <= r;++c)
