Parámetro: Array para la comparación
Devuelve: 1 : si a > b
-1 : si a < b
0 : si a = b
Ejemplo 1 :
# Ruby code for <=>() method
# checking equality
# declaring arrays
a = [18, 22, 33, 4, 5, 6]
# declaring arrays
b = [18, 22, 33, 4, 5, 6]
# declaring arrays
c = [18, 22, 33, 40, 50, 6]
# <=> method
puts "<=> method : #{a <=> b}\n\n"
# <=> method
puts "<=> method : #{a <=> c}\n\n"
# <=> method
puts "<=> method : #{b <=> c}\n\n"
Producción :
method : 0 method : -1 method : -1
Ejemplo #2:
# Ruby code for <=>() method
# checking equality
# declaring arrays
a = ["abc", "xyz", "dog"]
# declaring arrays
b = ["cat", "cat", "dog"]
# declaring arrays
c = ["cat", "cat", "dog"]
# <=> method
puts "<=> method : #{a <=> b}\n\n"
# <=> method
puts "<=> method : #{a <=> c}\n\n"
# <=> method
puts "<=> method : #{b <=> c}\n\n"
