How to create the repeat method:

[ne, "two", 3].repeat(3)

Result:

[ne, ne, ne, "two", "two", "two", 3, 3, 3]

Thanks.

Thanks.

I solve this using this method:

def repeat n
new_array = Array.new
self.each { |x| n.times do new_array.push x end }
new_array
end

Thanks.

Thanks.

like this?

irb(main):018:0> a=[ne,"two",3]
=> [ne, "two", 3]
irb(main):019:0> n=3; res=[]; a.each { |e| n.times { |i| res.push e } }; res
=> [ne, ne, ne, "two", "two", "two", 3, 3, 3]

Hi,

How to create the repeat method:

[ne, "two", 3].repeat(3)

Result:

[ne, ne, ne, "two", "two", "two", 3, 3, 3]

You can do it like this:

irb(main):003:0> [ne,"two",3].map{|x|[x]*3}.flatten(1)
=> [ne, ne, ne, "two", "two", "two", 3, 3, 3]

Regards,

Another way maybe,

class Array
def repeat(num)
Array.new(num,self).transpose.flatten
end
end

p [ne,"two",3].repeat(3) #> [ne, ne, ne, "two", "two",
"two", 3, 3, 3]

Another way maybe,

class Array
=A0def repeat(num)
=A0 =A0Array.new(num,self).transpose.flatten
=A0end
end

p [ne,"two",3].repeat(3) =A0 =A0#> [ne, ne, ne, "two", "two",
"two", 3, 3, 3]

This is nice!

Since we didn't have #inject in a long time:

module Enumerable
def repeat(n)
inject [] do |res, it|
n.times { res << it }
res
end
end
end

Kind regards
