Answer 1

def num_to_str(num:str):


	prefix = ('', 'double ', 'triple ', 'quadruple ')
	root = ('zero', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine')
	reapets = 0
	res = []
	for i in range(len(num)):
		if (i < (len(num)-1)) and (num[i] == num[i+1]):
			reapets += 1
		else:
			res.append(prefix[reapets] + root[int(num[i])])
			reapets = 0
	return ' '.join(res)
for i in range(3):
	number = input()
	res = []
	i = 4
	num = number[:4]
	while num:
		res.append(num_to_str(num))
		num = number[i:i+3]
		i += 3
	print(' '.join(res))
