Solution in Ruby (judge verdict: Wrong Answer)

 def sort_bubble(a)
 	n = a.size
	n = n -1
	 
	for i in 0..n
		for j in 0..n - i -1
			if a[j] > a[j+1]
				tmp = a[j]
				a[j] = a[j+1]
				a[j+1] = tmp
			end
		end
	end
	
	return a
	
end

 a = [0,0,0,0,0,0,0,0,0,0]
 
for num in 0..9 do
 
	a[num] = gets.chomp
 
end
 
for num in 0..2 do
	puts a[num]
end
