某石油公司计划建造一条由东向西的主输油管道。该管道要穿过一个有 n 口油井的油田。从每口油井都要有一条输油管道沿最短路经(或南或北)与主管道相连。如果给定 n口油井的位置,即它们的 x 坐标（东西向）和 y 坐标（南北向）,应如何确定主管道的最优位置,即使各油井到主管道之间的输油管道长度总和最小的位置?证明可在线性时间内确定主管道的最优位置,使得给定n口油井的位置,编程计算各油井到主管道之间的输油管道最小长度总和。 -An oil company plans to construct a east to west from the main pipeline. The pipeline to pass through an oil field n wells. Wells from each must have a pipeline along the shortest path (or South or North) connected with the competent Road. If given the location of oil wells in n, that is, their x coordinates (east-west) and y coordinates (north-south), should be how to determine the optimal position in charge of Road, even if the wells to the pipeline in charge of Road between the sum of the smallest length location? proved to be linear time in charge of Road to determine the optimal location, making a given n the location of oil wells, programmed to calculate the well-to-charge of Road between the length of the sum of the smallest oil pipeline.

通常的冒泡是单向的，而这里是双向的，也就是说还要进行反向的工作。 代码看起来复杂，仔细理一下就明白了，是一个来回震荡的方式。 写这段代码的作者认为这样可以在冒泡的基础上减少一些交换（我不这么认为，也许我错了）。 反正我认为这是一段有趣的代码，值得一看。-The bubble is usually a one-way, and here is a two-way, that is to say the job would also like to reverse. The complexity of the code look carefully you will understand the rationale for it is a shock the way back and forth. Author of Writing the code that this can reduce the bubble on the basis of the exchange (I do not think so, I may be wrong). Anyway, I think this is a fun code, worth a visit.
