计算集合中的重复次数，并将聚合结果合并到另一个集合中

def count_and_merge(collection):
    # 统计计算集合中每个元素的出现次数
    count_map = {}
    for item in collection:
        if item in count_map:
            count_map[item] += 1
        else:
            count_map[item] = 1
    
    # 将聚合结果合并到另一个集合中
    merged_collection = set()
    for item, count in count_map.items():
        merged_collection.add((item, count))
    
    return merged_collection

# 示例用法
calculation_collection = [1, 2, 3, 2, 1, 3, 4, 5, 4, 1]
result = count_and_merge(calculation_collection)
print(result)
