获取数组中计数最多的前三个反应

def get_top_three_reactions(arr):
    # Step 1: 计算每个元素的出现次数
    count_dict = {}
    for element in arr:
        if element in count_dict:
            count_dict[element] += 1
        else:
            count_dict[element] = 1

    # Step 2: 按值降序排序字典
    sorted_dict = sorted(count_dict.items(), key=lambda x: x[1], reverse=True)

    # Step 3: 取出前三个元素
    top_three_reactions = []
    for i in range(min(3, len(sorted_dict))):
        top_three_reactions.append(sorted_dict[i][0])

    return top_three_reactions
