HackerRank Ruby Hash Each Solution

Hello coders, In this post, you will learn how to solve HackerRank Ruby Hash Each 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.

Let’s get started with HackerRank Ruby Hash Each Solution

Problem Statement

You’ve seen the control structure each used on an array. Similarly, it is available for the Hash collection, as well.

On Hash, it works in two ways.

Consider the example

user = {“viv” : 10, “simmy” : 20, “sp2hari” : 30}

Using each, each element can be iterated as

user.each do |key, value|
# some code on individual key, value


user.each do |arr|
# here arr[0] is the key and arr[1] is the value

Your task is to use each and iterate through the collection and print the keyvalue pair in separate lines.


puts key
puts value

def iter_hash(hash)
    hash.each do |k, v|
        puts k
        puts v
