当字符串是多个单词时，将罗马数字转换为单词形式

def roman_to_word(roman_string):
    roman_dict = {
        "1": "One",
        "2": "Two",
        "3": "Three",
        "4": "Four",
        "5": "Five",
        # 其他罗马数字的映射
    }
    
    roman_list = roman_string.split(" ")
    word_list = []
    
    for roman_num in roman_list:
        if roman_num in roman_dict:
            word_list.append(roman_dict[roman_num])
    
    result = " ".join(word_list)
    return result

# 示例输入和输出
roman_string = "1 2 3 4 5"
result = roman_to_word(roman_string)
print(result)  # 输出: "One Two Three Four Five"
