  • 给定一个n位正整数a

    给定一个n位正整数a,去掉其中任意k<=n个数字后,剩下的数字按原次序排列成一个新的正整数。对于给定的n位正整数a和正整数k,设计一个算法找出剩下数字组成的新数最小的删数方案。

  • 光学设计软件zemax源码: This DLL models an nular aspheric surface as described in: "Annular surfaces in

    光学设计软件zemax源码: This DLL models an nular aspheric surface as described in: "Annular surfaces in annular field systems" By Jose M. Sasian Opt. eng. 36 (12) P 3401-3401 December 1997 This surface is essentially an odd aspheric surface with an offset in the aspheric terms. The sag is given by: Z = (c*r*r) / (1+(1-((1+k)*c*c*r*r))^ 1/2 ) + a*(r-q)^2 + b*(r-q)^3 + c*(r-q)^4 + ... Note the terms a, b, c, ... have units of length to the -1, -2, -3, ... power.

  • THIS is really two books in one: a tutorial and a reference manual for JDBC, the application program

    THIS is really two books in one: a tutorial and a reference manual for JDBC, the application programming interface that makes it possible for programmers to access databases from Java. The goal is to be useful to a wide range of readers, from database novices to database experts. Therefore, we have arranged the book so that information needed only by experts is separated out from the basic material. We hope that driver developers as well as application programmers and MIS administrators will find what they need. Because different sections are aimed at different audiences, we expect that few people will read every page. We have sometimes duplicated explanations in an effort to make reading easier for those who do not read all sections. This book will be most helpful to those who have some knowledge of the Java programming language and SQL (Structured Query Language), but one doesn t need to be an expert in either to understand the basic concepts presented here.
