ruby - simplify string multiply concatenation

Question

s is a string, This seems very long-winded - how can i simplify this? :

   if x === 2
      z = s
    elsif x === 3
      z = s+s
    elsif x === 4
      z = s+s+s
    elsif x === 5
      z = s+s+s+s
    elsif x === 6
      z = s+s+s+s+s

Thanks

Answer 1

z=''
(x-1).times do
 z+=s
end

Answer 2

Pseudo code (not ruby)

if 1 < int(x) < 7  then
   z = (x-1)*s

Answer 3

Something like this is the simplest and works (as seen on ideone.com):

puts 'Hello' * 3   # HelloHelloHello

s = 'Go'
x = 4
z = s * (x - 1)
puts z             # GoGoGo

Copy—Returns a new String containing integer copies of the receiver.
