Ex3-23 亲兄弟问题 « 问题描述: 给定n 个整数0 1 1 , , , n- a a a 组成的序列。序列中元素i a 的亲兄弟元素k a 定义为: min{ | } k i j n j j i a = a a ³ a < < 。 亲兄弟问题要求给定序列中每个元素的亲兄弟元素的位置。元素i a 的亲兄弟元素为k a 时,称k 为元素i a 的亲兄弟元素的位置。当元素i a 没有亲兄弟元素时,约定其亲兄弟元素 的位置为-1。 例如,当n=10,整数序列为6,1,4,3,6,2,4,7,3,5 时,相应的亲兄弟元素位 置序列为:4,2,4,4,7,6,7,-1,9,-1。 « 编程任务: 对于给定的n个整数0 1 1 , , , n- a a a 组成的序列,试用抽象数据类型栈,设计一个O(n) 时间算法,计算相应的亲兄弟元素位置序列。 « 数据输入: 由文件input.txt提供输入数据。文件的第1 行有1 个正整数n,表示给定给n个整数。 第2 行是0 1 1 , , , n- a a a 。 « 结果输出: 程序运行结束时,将计算出的与给定序列相应的亲兄弟元素位置序列输出到output.txt 中。 输入文件示例 输出文件示例 input.txt 10 4 2 4 4 7 6 7 -1 9 -1 output.txt 6 1 4 3 6 2 4 7 3 5

I made a lot of changed on this object,such as * // 1.Encapsulates all code in one userobjet,since PB does not * // support "Address of Function" , so we can not set new * // WndProc, just makes the object more easy to use. * // 2.Uses structure array instead of Datastore * // 3.Calc width of menuitem at runtime(MEASUREITEM) * // 4.Draw disabled status

JLAB is a set of Matlab functions I have written or co-written over the past fifteen years for the purpose of analyzing data. It consists of four hundred m-files spanning thirty thousand lines of code. JLAB includes functions ranging in complexity from one-line aliases to high-level algorithms for certain specialized tasks. These have been collected together and made publicly available for you to use, modify, and --- subject to certain very reasonable constraints --- to redistribute. Some of the highlights are: a suite of functions for the rapid manipulation of multi-component, potentially multi-dimensional datasets a systematic way of dealing with datasets having components of non-uniform length tools for fine-tuning figures using compact, straightforward statements and specialized functions for spectral and time / frequency analysis, including advanced wavelet algorithms developed by myself and collaborators.
