Answer 1

t = int(input('the number of test cases: '))
def family(t):
    flag = True
    total = []
    for i in range(t):
        res = []
        n = int(input('the total number of words: '))
        words = input('Words: ')
        for word in words.split(' '):
            res.append(word)
        if n != len(res):
            total.append('not a family')
        else:
            for word in range(1, len(res)):
                if len(res[word - 1]) - 1 == len(res[word]) or  len(res[word - 1]) + 1 == len(res[word]) or len(res[word - 1]) == len(res[word]):
                    continue
                else:
                    flag = False
                    total.append('not a family')
                    break
            if flag == True:
                for i in range(1, len(res)):
                    counter = 0
                    for j in res[i]:
                        if res[i].count(j) != res[i-1].count(j):
                            counter += 1
                        else:
                            continue
                    if counter != 1:
                        total.append('not a family')
                        break
                else:
                    total.append('family')
            else:
                continue
    return total
          


result = family(t)
for res in result:
    print(res)
