Question

RUBY!

\Write a method called reverse_each_word that takes in a string argument of a sentence and returns that same sentence with each word reversed in place.

First solve it using .each Then utilize the same method using .collect to see the difference.

For example:

1. reverse_each_word("Hello there, and how are you?")
2. #=> "olleH ,ereht dna woh era ?uoy"

Hint: You can't use an enumerator on a string, so how can we turn our string into an array?

Hint: How can we reverse each word and return those altered words? Remember that .each returns the original array but other enumerators don't.

Answer 1

reverse_each_word method using .each iterator :-

# function to reverse each word in a sentence
def reverse_each_word(str)
str1 = str.split(" ")
# splitting the sentence on the basis of space and storing it into a variable
ans = []
# answer array to store result
# iterating over elements of array using .each
str1.each do |i|
# pushing reversed word into answer array
ans.push(i.reverse)
end
# returning answer array after joing each item with a space
return ans.join(' ')
end
print(reverse_each_word("Hello there, and how are you?"))
