WTF I NEED HELP

Currently, the second .each will print out 5 five times (since it will print 5 for each item in the array, and there are five items). Modify the block so it will print each item in the array multiplied by five.

method that capitalizes a word

def capitalize(string)
puts “#{string[0].upcase}#{string[1…-1]}”
end

capitalize(“ryan”) # prints “Ryan”
capitalize(“jane”) # prints “Jane”

block that capitalizes each string in the array

[“ryan”, “jane”].each {|string| puts “#{string[0].upcase}#{string[1…-1]}”} # prints “Ryan”, then “Jane”

Im stuck

itś somekind of bug or an error, just refresh the webpage and you will have the rigth exercise.

[1, 2, 3, 4, 5].each { |i| puts 5 }

this one can be solved multiplying every item by 5 like this

[1, 2, 3, 4, 5].each { |i| puts i*5 }

I tried:

[1, 2, 3, 4, 5].each { |i| puts i * 5 }

[1, 2, 3, 4, 5].each { |i| }

as a result, I received:
5
10
15
25

system allowed me to proceed to next exercise.

not sure if I am correct, but the solution it gave did not make sense to me or give the answer : 5, 10, 15, 25

Put in the same solution and got the correct results. Late reply lol but yeah your answer is correct it seems.

I don’t know if you’ll get this, or even, if you are still stuck on it?
But from what I understand:

[1, 2, 3, 4, 5].each { |i|
Means each array in [ ] becomes a ‘placeholder name’ as ‘i’.

.each { |i| puts i * 5 }
Means for each ‘i’, times it by 5.
so it now becomes:
1 x 5
2x 5
3x 5
4x 5
5x 5
which in order, the answer to those calculation will be…
5
10
15
25

I hope that makes sense :slight_smile:
