红宝石 |哈希 < 方法
Hash#<()是比较两个 Hash 值的 Hash 类方法。
Syntax: Hash.<()
Parameter: Hash values
Return: true – if a < b otherwise return false
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
