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.

字符串函数在计算机编程语言中用于操作字符串或查询有关信息的字符串 （一些做两个）。 有字符串数据类型的大多数编程语言将会有一些字符串函数，虽然可能有其他低级方法内的每种语言直接处理字符串。在面向对象语言中，字符串函数通常实现为字符串对象的属性和方法。在基于列表的功能和语言中字符串表示为 （字符代码） 的列表，因此所有列表操作程序可以都考虑字符串函数。然而这种语言可能实现，以及明确的字符串特定功能的一个子集。 最基本的实例的字符串是函数的length(string)函数。此函数返回字符串的长度。
