Hello coders, In this post, you will learn how to solve HackerRank Ruby Hash Initialization Solution. This problem is a part of the Ruby Tutorial series. One more thing to add, don’t straight away look for the solutions, first try to solve the problems by yourself. If you find any difficulty after trying several times, then look for the solutions.
HackerRank Ruby Hash Initialization Solution
Let’s get started with Ruby Hash Initialization Solution
Problem Statement
Hashes, also called associative arrays, are dictionary-like data structures which are similar to arrays. Instead of using integers to index an object, however, hashes use any object as its index.
In this challenge, your task is to create three different Hash collections as explained below.
- Initialize an empty Hash with the variable name
empty_hash
Hint
empty_hash = Hash.new
- Initialize an empty Hash with the variable name
default_hashand the default value of every key set to1.
Hint
default_hash = Hash.new(1)
or
default_hash = Hash.new
default_hash.default = 1
- Initialize a hash with the variable name
hackerrankand having the key-value pairs"simmy", 100 "vivmbbs",200
Hint
hackerrank = {“simmy” => 100, “vivmbbs” => 200}
Hash can be defined using a new method
hackerrank = Hash.new
hackerrank[“simmy”] = 100
hackerrank[“vivmbbs”] = 200
HackerRank Ruby Hash Initialization Solution
# Initialize 3 variables here as explained in the problem statement
empty_hash = Hash.new
default_hash = Hash.new(1)
hackerrank = {"simmy" => 100, "vivmbbs" => 200}Note: This problem (Ruby Hash – Initialization) is generated by HackerRank but the solution is provided by Chase2Learn. This tutorial is only for Educational and Learning purpose.
