WHAT MIME64 IS: MIME64 is an encoding described in RFC1341 as MIME base64.Its purpose is to encode binary files into ASCII so that they may be passedthrough e-mail gates. In this regard, MIME64 is similar to UUENCODE.Although most binaries these days are transmitted using UUENCODE, Ihave seen a few using MIME64, and I have had requests from friends thatI decode MIME64 files that have fallen into their hands. As long assome MIME64 continues to exist, a package such as this one is usefulto have.

一、前言
24点游戏是一个常见游戏,出题者给出4个整数,要求答题者在指定时间内给出一个四则运算的表达式,恰好用上这这个整数各一次,计算结果为24,超出时间为输。
二、分析
用计算机来算这个题,搜索速度当然有很大优势,我编程喜欢考虑通用一点,不限制输入数量和结果数,甚至不限制运算符数量。这样组合数就很大,如果输入数比较多,则搜索时间会非常长。
我用两个方法来提高搜索速度:一、是大家都能考虑到的重复搜索问题,比如1,2,3和2,3,1所有的组合情况是相同的,我只搜索使用递增序的数组,则可以降低一个组合数的数量级别;二、使用动态规划中的备忘录方法,比如你计算出2和3所有可能的计算结果,则他们与4结合的时候,要用到,与1结合的时候,也要用到,使用备忘录,可以只计算一次,大大降低运算复杂度。
三、设计
整体设计:分别设计4个类:游戏、表达式、运算、分数,各司其责,结构清晰,易于扩展。
-First, the preamble
24-point game is a common game, give the title are four integer requiring answer within a specified period of time in a four calculations give the expression, just use that the integral of the time, results for the 24, beyond the time to lose.
Second, analysis
Use computers to count the title, the search speed of course, there is a great advantage, I enjoy taking generic programming that does not restrict the importation of the volume and the number of results, and even limiting the number of operators. So on a large number of combinations, if you
