Ruby | Array <=> function

Array#() : () is an Array class method which performs the comparison between the two arrays.

Syntax: Array.()

Parameter: Array for the comparison

Return: 1 : if a > b
-1 : if a < b
0 : if a = b

Example #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"

Output :

 method : 0

 method : -1

 method : -1

Example #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"

Output :

 method : -1

 method : -1

 method : 0
