使用codelsize 20:
注释/如何运作?
由于不可能使用数组或字符串作为输入,因此该程序通过将一系列整数(表示ascii字符)作为输入来工作。我最初考虑使用字符输入,但一直在努力寻找一种很好的终止解决方案,因此现在当输入小于1的任何数字时终止。最初它只是终止的负值,但是在编写程序后我不得不更改初始化,所以现在我不能满足要求的值2
,只能是1
(跟踪图像上的26/45)。但这并不重要,因为根据挑战规则,仅允许可打印的ASCII字符。
在重新进入循环过程中苦苦挣扎了很长时间,尽管最后我发现了相当优雅的解决方案。否pointer
或没有switch
操作,只有解释器碰壁,直到它转换回绿色编码解码器以读取输入(跟踪图像上的43-> 44)。
通过首先复制输入,加1,然后检查它是否大于1,来实现循环终止。如果是,则触发编解码器选择器,并在较低的路径上继续执行。如果不是,程序将继续向左继续(明亮的黄色代码,跟踪图像上的31/50)。
支持的输入大小取决于解释器实现,尽管可以使用正确的解释器来支持任意大的输入(例如,使用BigInteger
内部解释器的Java解释器)
刚才看到的设置包括一个不必要的DUP
和CC
(在跟踪图像7-> 8-> 9)。不知道那是怎么回事。这实际上是一个noop,它将代码选择器切换16次,这不会导致更改。
