Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.

最不幸的是，我不懂Haskell。如果我修改了测试用例，原翻译者的解决方案将无效，导致无法重新发布。

You ban fa, rang ourjinxin qu bian ji yi xia jiu hao le :D
@myjinxin2015 有办法能改过来吗？>_<
抱歉，Haskell版本有点问题，翻译者弄错了两个固定测试用例。
because it IS "cxgdba" (as stated in the example tests... ;) )
Reset the trainer if it's not what you have (do not forget to copy your code before, otherwise you will lose it)
why middlePermutation "abcdxg"
shouldBe"cgxdba"?Sorting with dictionary order, shouldn't it be "cxgdba"?
I'm really confused...
