    answer= []
    # first_letter = ''
    for word in s:
        word2 = []
        for i in range(len(word)):
            if i==0:
                word2.append(word[i].upper())
            else:
                word2.append(word[i].lower())
        result = "".join(word2)
        answer.append(result)
    answer = " ".join(answer)
    return answer
