我的问题是转向:

 iSort :: Ord a => [a] -> [a]
 iSort [] = []
 iSort (x:xs) = ins x (iSort xs)

 ins x [] = [x]
 ins x (y:ys)
   | x <= y    = x : y : ys
   | otherwise = y : ins x ys

在一个跟踪它进行比较的次数的解决方案中,这里是我需要生成的代码的框架:

 iSortCount :: Ord a => [a] -> (Integer, [a])
 iSortCount [] = ...
 iSortCount (x:xs) = ...

 insCount x (k, [])     = ... 
 insCount x (k, (y:ys)) -- Count the times when it …
