answer:在处理大数据时，可以考虑使用迭代替代递归来改进程序。递归在大数据集下可能会导致栈溢出的问题，而迭代可以更有效地处理大量的数据。 另外，你可以考虑使用更高效的数据结构来存储价格列表，例如使用数组或者链表代替列表。数组的访问和操作速度更快，而链表可以更有效地处理大量的插入和删除操作。 还可以尝试对算法进行优化，避免不必要的计算和重复计算。例如，可以使用动态规划来避免重复计算最小价格差。 此外，当处理大数据时，可以考虑使用多线程或者并行计算来加速程序的运行。通过同时处理多个数据，可以提高程序的处理速度。 最后，如果可能的话，使用可扩展性的计算平台，如分布式计算框架或云计算平台，可以更好地处理大数据集。

answer:"American Woman Part 3" is a fictional story and there is no widely known specific storyline under that title. It is possible that there may be different movies, books, or songs with similar titles, so without more context, it is difficult to say precisely what "American Woman Part 3" refers to.

answer:I apologize for the confusion in my previous response. To clarify, "American Woman" is a novel by Susan Choi, and there is no official "Part 3" of the book. "American Woman" is a work of historical fiction that tells the story of a young woman named Jenny Shimada, who becomes involved with a radical political group called the Weather Underground in the 1970s. The novel explores Jenny's journey as she finds herself on the run, hiding from authorities and questioning her loyalty to the cause. It delves into themes of identity, love, and the power of ideology. However, there is no known specific "Part 3" of the novel; it is a single, standalone book.
