各位大侠,研究一狗算法候遇到问题,困扰很久,哪位大侠能帮忙研究一下感激不尽

a.变换前的数组(10进制):,108,105,109,114,80,242,136,5,80,244,136,5,
b.变换前的数组长度(16进制):,0000000C
c.变换后的数组(10进制):80,242,136,5,80,244,136,5,
d.变换后的数组长度(16进制):00000008

说明:a是一个数组,这个数组在经过一个算法后变成最终的c数组
c数组的长度永远=a数组长度-4
要求是求出a数组变换成c数组的算法.

以下的列表第一行是a,第二行是b,第三行是c,d被我省略了.因为d=b-4

一点提示:
    你贴的是变换算法,一般一定还会有一个“逆变换”算法与之对应。“逆变换”算法应该是将变换后的数据“逆变换”成原来数据。
    所以,我认为对付这种使用方法,可以自己做:变换-逆变换 2个算法放到狗中,只要输出的变换长度对应就可以了。至于原狗中怎样实现的变换-逆变换算法,根本不用管它,只要自己仿写的变换-逆变换的输入与输出与原狗的功能一样可以了。

你说的有道理.但对这个case不适用:
1)软件把a给锁,锁把a-c给程序,程序用的是c,不是把c再逆变换成a使用.所以逆变换算法无法从程序中debug得到.
2)看你的意思是长度一样变换算法就一样.但可惜并不是如此,上面的列表中长度一样变换不一样的就有.我的分析:变换与长度没有必然关系.否则管他3721直接做个矩阵去校验匹对就ok
3)算法的实现与原狗可以不一样.但结果一样即可.比如原狗算法6+4=10,我的算法可以是3+7=10也可以是2*5=10,只要结果是10就足够了.
4)困扰很久了,真是麻烦.智能狗真的比传统狗难缠
