This is a continuation of Converting Celsius to Fahrenheit with Python, and TypeScript, and Go but in Ruby:
def c2f(c)
c * 9.0 / 5 + 32;
end
def is_mirror(a, b)
def massage(n)
if n < 10
"0#{n}"
elsif n >= 100
massage(n - 100)
else
n.to_s
end
end
massage(a).reverse == massage(b)
end
def print_conv(c, f)
puts "#{c}°C ~= #{f}°F"
end
(4...100).step(12).each do |c|
f = c2f(c)
if is_mirror(c, f.ceil)
print_conv(c, f.ceil)
elsif is_mirror(c, f.floor)
print_conv(c, f.floor)
else
break
end
end
Run it like this:
ruby conversion.rb
and the output becomes:
4°C ~= 40°F 16°C ~= 61°F 28°C ~= 82°F 40°C ~= 104°F 52°C ~= 125°F
