How to print Pyramid Pattern in Ruby

How to print Pyramid Pattern in Ruby ?

Answer

To print a pyramid pattern in Ruby, you can use nested loops where the outer loop controls the rows and the inner loops control the spaces and stars printed in each row.

✐ Examples

1 Pyramid Pattern with Asterisks (*)

In this example,

We define a method print_pyramid that takes an integer n as input to represent the number of rows in the pyramid.
We use nested loops where the outer loop controls the rows and the inner loops control the spaces and stars printed in each row.
Inside the inner loops, we use conditions to determine whether to print a space or a star (*) based on the pyramid pattern.
After each row, we use puts to move to the next line.

Ruby Program

def print_pyramid(n)
  n.times do |i|
    print ' ' * (n - i - 1)
    puts '*' * (2 * i + 1)
  end
end

print_pyramid(5)

Output

    *
   ***
  *****
 *******
*********
