To print a Hollow Square Pattern in Ruby, you can use nested loops. The outer loop controls the rows, and the inner loop controls the columns. Conditions are used to determine whether to print stars or spaces for the pattern.
In this example,
print_hollow_square
that takes the side length n
as a parameter.for
loops, one for rows and one for columns, to iterate through each cell of the square.*
) for the border and spaces (
) for the inside.print_hollow_square
with the desired side length to print the pattern.def print_hollow_square(n)
n.times do |i|
row = ''
n.times do |j|
if i == 0 || i == n - 1 || j == 0 || j == n - 1
row += '*'
else
row += ' '
end
end
puts row
end
end
side_length = 5
print_hollow_square(side_length)
