我想知道我是否可以将字符串转换为字符列表？

"jt5x=!" -> ["j","t","5","x","=","!"]

基本上,它会是？

example :: String -> [Char]

我写了这段代码,它是关于两个字符串是否是另一个字符串:

anagram :: String->String->Bool            
anagram w1 w2 = anagram1 x1 x2
where 
    y1 = break w1
    y2 = break w2
    x1 = quicksort y1
    x2 = quicksort y2


anagram1 :: [String]->[String]->Bool
anagram1 (h1:t1)(h2:t2)
    | h1!=h2 = False
    | h1==h2 = anagram1 t1 t2
    | otherwise = True  

我在那里找到了quicksort的代码http://c2.com/cgi.com/wiki?QuickSortInHaskell

quicksort :: [String]->[String]
quicksort [] = []
quicksort (h:t) = quicksort small ++ (h : quicksort(large))
   where
      small = [y | y <- t, y <= h]
      large = [y | …
