ruby 合并 json

This problem is all about **finding a way to merge two sets**. We have tried to find the solution with the help of two ways. Ruby is very rich in library. It has various predefined methods that are purposefully defined to fulfill some purpose. Here, for **merging two sets**, we can take help from the **merge() method** which is predefined in Ruby's library. Let us see the ways through which we are completing the task. We have two merge two sets or you can say that we have to store elements of two sets in the same or another set.

这个问题全是关于**寻找一种方法来合并两个集合** 。 我们尝试通过两种方法来找到解决方案。 Ruby的库非常丰富。 它具有各种预定义的方法，这些方法被有目的地定义为实现某些目的。 在这里，为了**合并两个集合** ，我们可以从Ruby库中预定义的**merge()方法获得**帮助。 让我们看看完成任务的方式。 我们有两个合并两个集合，或者可以说我们必须将两个集合的元素存储在同一集合或另一个集合中。

**Methods used:**

**使用的方法：**

*  **Set.new**: This method is used to create a new instance of Set class.
    
    **Set.new** ：此方法用于创建Set类的新实例。
 *  **Set.each**: This method is used to fetch an individual element from the Set.
    
    **Set.each** ：此方法用于从Set中获取单个元素。
 *  **Set.add()**: **Set.add** method is predefined in Ruby's library which is used to add new elements in the Set.
    
    **Set.add()** ： **Set.add**方法是在Ruby的库中预定义的，用于在Set中添加新元素。
 *  **Set.merge()**: This method is used to merge the set which is provided as the argument with the Set from which it is invoked.
    
    **Set.merge()** ：此方法用于将作为参数提供的集合与调用它的Set合并。

**Variables used:**

**使用的变量：**

*  Vegetable: This is the first instance of Set class. It contains the name of vegetables.
    
    Vegetable ：这是Set类的第一个实例。 它包含蔬菜的名称。
 *  Fruits: This is the second instance of Set class. It contains the name of fruits.
    
    水果 ：这是Set类的第二个实例。 它包含水果的名称。
 *  i: This variable is used to specifying the serial of the Set. It is used inside the Set.each method.
    
    i ：此变量用于指定Set的序列号。 它在Set.each方法内使用。

**Example 1:**

**范例1：**

=begin
    Ruby program to merge two sets.
    =end
    require 'set'
    
    Vegetable=Set.new(["potato","brocolli","broccoflower","lentils","peas","fennel","chilli","cabbage"])
    
    Fruits = Set.new(["Apple","Mango","Banana","Orange","Grapes"])
    
    Vegetable.each do |element|
        Fruits.add(element)
    end
    
    i = 1
    Fruits.each do |element|
    	puts "#{i} => #{element}"
    	i = i + 1 
    end

**Output**

**输出量**

1 => Apple
    2 => Mango
    3 => Banana
    4 => Orange
    5 => Grapes
    6 => potato
    7 => brocolli
    8 => broccoflower
    9 => lentils
    10 => peas
    11 => fennel
    12 => chilli
    13 => cabbage

**Explanation:**

**说明：**

In the above code, we are using the **Set.each** method to **merge two sets**. We are using multiple methods for this purpose. We are also using the **Set.add()** method to add the element from one Set to another one. You can also observe the Set which is getting updated is the Fruit set.

在上面的代码中，我们使用**Set.each**方法**合并两个set** 。 为此，我们正在使用多种方法。 我们还使用**Set.add()**方法将元素从一个Set添加到另一个Set。 您还可以观察到正在更新的Set是Fruit set。

**Example 2:**

**范例2：**

=begin
    Ruby program to merge two sets.
    =end
    
    require 'set'
    
    Vegetable=Set.new(["potato","brocolli","broccoflower","lentils","peas","fennel","chilli","cabbage"])
    
    Fruits = Set.new(["Apple","Mango","Banana","Orange","Grapes"])
    
    Vegetable.merge(Fruits)
    
    i = 1
    Vegetable.each do |element|
    	puts "#{i} => #{element}"
    	i = i + 1 
    end

**Output**

**输出量**

1 => potato
    2 => brocolli
    3 => broccoflower
    4 => lentils
    5 => peas
    6 => fennel
    7 => chilli
    8 => cabbage
    9 => Apple
    10 => Mango
    11 => Banana
    12 => Orange
    13 => Grapes

**Explanation:**

**说明：**

In the above code, we are taking help from Set.merge() method. The task gets pretty simple and can be done in a single line. The resultant set is stored in Vegetable set. You can also do Fruits.merge (Vegetables) if you want to store the result in the Fruit set. At last, we are printing the set with the help of Set.each method.

在上面的代码中，我们从Set.merge()方法获得帮助。 该任务变得非常简单，可以在一行中完成。 结果集存储在蔬菜集中。 如果要将结果存储在水果集中，也可以执行Fruits.merge (蔬菜)。 最后，我们将借助Set.each方法打印集合。
