store the value in array and return the function ruby

问题

I understand your request. Here's the translated code and the modified function:

  1. # 项目包含哈希数组，示例：
  2. item = [{item1},{item2},{item3}]
  4. def function1
  5.    item.map( other_class.call ).flatten
  6. end
  8. # 其他类将返回包含字符串的数组
  9. class other_class
  10.    def call
  11.      # 返回字符串数组的方法
  12.    end
  13. end
  15. # 目前，function1 返回一个包含字符串值的数组的数组。
  17. # 期望输出 = ["str1", "str2", "str3", "str4", "str5"]
  19. # 有没有办法修改上述方法？

The modification to the function1 method involves adding the .flatten method to the result of item.map(other_class.call) to convert the array of arrays into a flat array of strings. This will give you the expected output.

英文:

item has array of hash. ex.
item = [{item1},{item2},{item3}]

  1. def function1
  2.    item.map( other_class.call )
  3. end
  5. # other class will return the array which contains string
  6. class other_class
  7.    def call 
  8.      #method which return arrray of strings
  9.    end
  10. end

currently the function1 is returning the array of array which has string values.

function1 output example [["str1"], [], ["str2"], ["str3"], ["str4","str5"]]

I want to modify the function1 which will return the array of string.

  1. expected output = ["str1" "str2", "str3", "str4", "str5"]

Guys, any idea how can I modify the above method.

Thanks in advance.

得分: 1

Output

  1. ["str1", "str2", "str3", "str4", "str5"]

So you should write something like

  1. def function1
  2.    other_class.call.flatten
  3. end
英文:

Input

  1. item=[["str1"], [], ["str2"], ["str3"], ["str4","str5"]]

Code

  1. p item.flatten

output

  1. ["str1", "str2", "str3", "str4", "str5"]

So you should write something like

  1. def function1
  2.    other_class.call.flatten
  3. end
