ruby .set函数

## 在Ruby中进行比较 **(**Set comparison in Ruby**)** ##

Ruby provides you various methods through which you can carry out **comparison operations** within two sets. Now, let us go through various methods and understand their implementation with the help of their syntax and examples.

Ruby为您提供了各种方法，您可以通过它们在两组中执行**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。

### ==运算子 **(**== operator**)** ###

This operator returns true when both the sets are equal or you can say that for the value to be true, set2 must be having the same values as of set1.

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，则set2必须具有与set1相同的值。

**Syntax:**

**句法：**

Set1 == Set2

**Example:**

**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

**Output**

**输出量**

Vegetable is equal to Sabzi

### <运算符 **(**< operator**)** ###

This operator is an alias for the proper subset. This operator will return true when Set2 is having all the elements which are present in Set1. Set2 may or may not have more elements.

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可以具有或可以不具有更多元素。

**Syntax:**

**句法：**

Set2 < Set1

**Example:**

**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

### >运算子 **(**> operator**)** ###

This operator is an alias for a proper superset. This operator will return true when Set1 is having all the elements which are present in Set2. Set1 may or may not have more elements.

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可能有也可能没有更多元素。

**Syntax:**

**句法：**

Set2 > Set1

**Example:**

**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

**Output**

**输出量**

Vegetable is not a superset of Sabzi

### .subset？() **(**.subset?()**)** ###

This operator is an alias for a proper superset. This operator will return true when Set1 is having all the elements which are present in Set2. Set1 may or may not have more elements.

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可能有也可能没有更多元素。

**Syntax:**

**句法：**

set1.subset?(set2)

**Example:**

**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

**Output**

**输出量**

Vegetable is not a subset of Sabzi

### .superset？() **(**.superset?()**)** ###

The working of this method is the same as of < operator as > operator is an alias for this method. This method is implemented in the following manner:

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：

**Syntax:**

**句法：**

set1.superset?(set2)

**Example:**

**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

**Output**

**输出量**

Vegetable is a superset of Sabzi
