I have this code: var s1 = new Subject<Unit>(); var s2 = new Subject<Unit>(); var ss = s1.Merge(s2).Finally(() => Console.WriteLine(\"Finished!\"));
In order to learn what a fixed-point combinator is and is used for, I wrote my own. But instead of writing it with strictly anonymous functions, like Wikipedia\'s example, I just used define:
It seems like scala\'s parser combinators don\'t backtrack. I have a grammar (see bottom) which can\'t parse the following \"stmt\" correctly:
I try to write a parser in scala using Parser Combinators. If I match recursively, def body: Parser[Body] =
I have datatype: data SidesType = Sides Int Int Int deriving (Show) And I need a function which get a list of SidesType and remove duplicates from it.
iterate :: (a -> a) -> a -> [a] (As you probably know) iterate is a function that takes a function and starting value. Then it applies the function to the starting value, the开发者_StackOve
I wanted to test foldl vs foldr. From what I\'ve seen you should use foldl over foldr when ever you can due to tail reccursion optimization.
Which of the following are you most likely to write? r = zip xs $ map sqrt xs or r = [(x, sqrt x) | x <- xs]
The code for the myAny function in this question uses foldr.It stops processing an infinite list when the predicate is satisfied.
Suppose I have an ambiguous language expressed in combinator parser. Is there a way to make certain expressions locally greedy? Here\'s an example of what I mean.
