红宝石 |哈希 < 方法

Hash#<()是比较两个 Hash 值的 Hash 类方法。

示例 #1:

# Ruby code for Hash.<() method
  
# declaring Hash value
a = {a:100, b:200}
  
# declaring Hash value
b = {a:100, c:300, b:200}
  
# declaring Hash value
c = {a:100}
  
# COMPARING TWO Hash VALUES
puts "Hash a < b : #{a

输出 :

Hash a < b : true

Hash b < c : false

Hash a < c : true

示例 #2:

# Ruby code for Hash.<() method
  
# declaring Hash value
a = { "a" => 100, "b" => 200 }
  
# declaring Hash value
b = {"a" => 100}
  
# declaring Hash value
c = {"a" => 100, "c" => 300, "b" => 200}
  
# COMPARING TWO Hash VALUES
puts "Hash a < b : #{a

输出 :

Hash a < b : false

Hash b < c : true

Hash a < c : false
