How to print Diamond Pattern in Ruby ?

Answer

To print a Diamond Pattern in Ruby, we use nested loops. The outer loop controls the rows and the inner loops control the spaces and stars (*) to form the pattern.

✐ Examples

1 Diamond Pattern

In this example,

We define a function print_diamond that takes the desired number of rows n as a parameter.
We use two nested for loops, where the outer loop runs from 1 to n and the inner loops control the spaces and stars in each row.
Within the inner loops, we calculate the number of spaces and stars based on the current row number to form the diamond pattern.

Ruby Program

def print_diamond(n)
  (1..n).each do |i|
    puts ' ' * (n - i) + '*' * (2 * i - 1)
  end
  (n - 1).downto(1) do |i|
    puts ' ' * (n - i) + '*' * (2 * i - 1)
  end
end

# Example usage
print_diamond(5)

Output
