元组数组中最常见的值。不区分大小写

def most_common_value(tuple_array):
    count_dict = {}  # 统计元素出现次数的字典
    max_count = 0  # 最大出现次数
    most_common = None  # 最常见的值

    # 遍历元组数组，将元素转换为小写或大写，并统计出现次数
    for element in tuple_array:
        element = element.lower()  # 转换为小写
        if element in count_dict:
            count_dict[element] += 1
        else:
            count_dict[element] = 1

        # 更新最大出现次数和最常见的值
        if count_dict[element] > max_count:
            max_count = count_dict[element]
            most_common = element

    return most_common

# 测试示例
tuple_array = ("apple", "banana", "Apple", "orange", "apple", "BANANA", "apple")
result = most_common_value(tuple_array)
print("元组数组中最常见的值是:", result)

元组数组中最常见的值是: apple
