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.
In this example,
print_diamond
that takes the desired number of rows n
as a parameter.for
loops, where the outer loop runs from 1 to n
and the inner loops control the spaces and stars in each row.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)
