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

    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
