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.
HackerRank Ruby Hash Each Solution
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
end
or
user.each do |arr|
# here arr[0] is the key and arr[1] is the value
end
Your task is to use each and iterate through the collection and print the key–value pair in separate lines.
Hint
puts key
puts value
HackerRank Ruby Hash Each Solution
def iter_hash(hash)
hash.each do |k, v|
puts k
puts v
end
endNote: This problem (HackerRank Ruby Hash Each) is generated by HackerRank but the solution is provided by Chase2Learn. This tutorial is only for Educational and Learning purpose.
