从字符串数组中删除项目

def remove_duplicates(input_str_array):
    # 使用哈希表存储每个元素及其出现次数
    str_dict = {}
    for i in input_str_array:
        if i in str_dict:
            str_dict[i] += 1
        else:
            str_dict[i] = 1

    # 将出现次数为 0 的元素添加到新的字符串数组中
    result = []
    for key, value in str_dict.items():
        if value == 0:
            result.append(key)

    return result
