Problem Statement

Load a JSON string into a data structure.
Also, create a new data structure and serialize it into JSON. Use objects and arrays (as appropriate for your language) and make sure your JSON is valid (https://jsonformatter.org).

Let's start with the solution:

Step by Step solution about How to resolve the algorithm JSON step by step in the Ruby programming language

The provided Ruby code demonstrates how to use the JSON library to parse JSON-formatted data into a Ruby object, modify the object, and convert it back to JSON. Here's a breakdown of the code:

  1. require 'json': This line imports the JSON library, which provides methods for working with JavaScript Object Notation (JSON) data.

  2. ruby_obj = JSON.parse('{"blue": [1, 2], "ocean": "water"}'): This line uses the JSON.parse method to parse a JSON string into a Ruby object. The JSON string represents an object with two key-value pairs: "blue" mapped to an array of integers [1, 2] and "ocean" mapped to the string "water." The result is stored in the ruby_obj variable.

  3. puts ruby_obj: This line prints the contents of the ruby_obj variable to the console. The output would be:

{"blue"=>[1, 2], "ocean"=>"water"}
  1. ruby_obj["ocean"] = { "water" => ["fishy", "salty"] }: This line modifies the ruby_obj by assigning a new value to the "ocean" key. The new value is a hash with a single key-value pair: "water" mapped to an array of strings ["fishy", "salty"]. This effectively replaces the original "ocean" string value.

  2. puts JSON.generate(ruby_obj): This line uses the JSON.generate method to convert the modified ruby_obj back into a JSON string. The result is printed to the console. The output would be:

{"blue":[1,2],"ocean":{"water":["fishy","salty"]}}
  1. puts JSON.pretty_generate(ruby_obj): This line uses the JSON.pretty_generate method to generate a formatted JSON string from ruby_obj. This method adds indentation and line breaks to the JSON output for better readability. The output would be:
{
 "blue": [
   1,
   2
 ],
 "ocean": {
   "water": [
     "fishy",
     "salty"
   ]
 }
}

This code illustrates how to manipulate data using JSON in Ruby, including parsing, modifying, and converting back to JSON in both plain and formatted forms.

Source code in the ruby programming language

require 'json'

ruby_obj = JSON.parse('{"blue": [1, 2], "ocean": "water"}')
puts ruby_obj

ruby_obj["ocean"] = { "water" => ["fishy", "salty"] }
puts JSON.generate(ruby_obj)
puts JSON.pretty_generate(ruby_obj)
