在Ruby中进行比较

Ruby提供了各种方法，通过它们可以在两组中执行比较操作。现在，让我们看一下各种方法，并借助它们的语法和示例了解它们的实现。

==运算符

当两个集合相等时，该运算符将返回true；或者您可以说，要使该值为true，set2必须具有与set1相同的值。

语法：

    Set1 == Set2

示例

=begin
Ruby program to show ==
=end

require 'set'

Vegetable = Set.new(["potato", "tomato","brinjal","onion"])

Sabzi = Set.new(["potato", "tomato","brinjal","onion"])

bool = Vegetable == Sabzi

if bool == true
	puts "Vegetable is equal to Sabzi"
else
	puts "Vegetable is not equal to Sabzi"
end

输出结果

Vegetable is equal to Sabzi

<运算符

该运算符是适当子集的别名。当Set2具有Set1中存在的所有元素时，此运算符将返回true。Set2可能有也可能没有更多元素。

语法：

    Set2 < Set1

示例

=begin
Ruby program to show < operator
=end

require 'set'

Vegetable = Set.new(["potato" , "tomato" , "brinjal" , "onion"])

Sabzi = Set.new(["potato" , "tomato" , "brinjal" , "onion" , "beetroot"])

bool = Vegetable < Sabzi

if bool == true
	puts "Vegetable is a subset of Sabzi"
else
	puts "Vegetable is not a subset to Sabzi"
end

>运算符

该运算符是适当超集的别名。当Set1具有Set2中存在的所有元素时，此运算符将返回true。Set1可以具有或可以不具有更多元素。

语法：

    Set2 > Set1

示例

=begin
Ruby program to show > operator
=end

require 'set'

Vegetable = Set.new(["potato", "tomato","brinjal","onion"])

Sabzi = Set.new(["potato", "tomato","brinjal","onion","beetroot"])

bool = Vegetable > Sabzi

if bool == true
	puts "Vegetable is a superset of Sabzi"
else
	puts "Vegetable is not a superset of Sabzi"
end

输出结果

Vegetable is not a superset of Sabzi

.subset？()

该运算符是适当超集的别名。当Set1具有Set2中存在的所有元素时，此运算符将返回true。Set1可以具有或可以不具有更多元素。

语法：

    set1.subset?(set2)

示例

=begin
Ruby program to show subset method
=end

require 'set'

Vegetable = Set.new(["potato", "tomato","brinjal","onion","peas"])

Sabzi = Set.new(["potato", "tomato","brinjal","onion","beetroot"])

bool = Vegetable.subset?(Sabzi)

if bool == true
	puts "Vegetable is a subset of Sabzi"
else
	puts "Vegetable is not a subset of Sabzi"
end

输出结果

Vegetable is not a subset of Sabzi

.superset？()

此方法的工作方式与<运算符相同，因为>运算符是此方法的别名。此方法以以下方式实现：

语法：

    set1.superset?(set2)

示例

=begin
Ruby program to show superset method
=end

require 'set'

Vegetable = Set.new(["potato", "tomato","brinjal","onion","peas","beetroot"])

Sabzi = Set.new(["potato", "tomato","brinjal","onion","beetroot"])

bool = Vegetable.superset?(Sabzi)

if bool == true
	puts "Vegetable is a superset of Sabzi"
else
	puts "Vegetable is not a superset of Sabzi"
end

输出结果

Vegetable is a superset of Sabzi
