# declaring array 
b = [1, 4, 1, 1, 88, 9]

puts "shuffle!() method form : #{a.shuffle!()}\n\n"
  
puts "shuffle!() method form : #{b.shuffle!()}\n\n"
  
puts "shuffle!() method form : #{c.shuffle!()}\n\n"

Output :

shuffle!() method form : [5, 6, 22, 33, 18, nil]

shuffle!() method form : [1, 4, 9, 1, 1, 88]
