心里堵了一下，改了个wingide破解文件

这两天将wingide更新一下，虽然还是可以在python2.x的环境下破解，心里堵了一下，就改出了一个在python3.x下运行的破解文件。

fromdigits string (which is in order of smallest to largest
digit). The return value is a string of elements from todigits
(ordered in the same way). The input and output bases are
determined from the lengths of the digit strings. Negative
signs are passed through.

途中遇见：
求为双数时：

在python2.7版本中：i / 2 * 2 == i
在python3.4版本中：i % 2 == 0

除法：
在python2.7版本中：52459687811034700543723/30=1748656260367823351457
在python3.4版本中：52459687811034700543723/30=174865626036782340505
可以看到在 3.4.1 的解释器里，“/”的结果保留了小数位，而“//”则是取整后的结果。
这是stackoverflow的问题：Python2.x 的版本里强制除法的结果为浮点数；3.x 里面并不存在这样的问题。
