I often hear开发者_开发百科 people say that C doesn\'t perform tail call elimination.Even though it\'s not guaranteed by the standard, isn\'t it performed in practice by any decent implementation anyh
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.
If I recall correctly, tail recursive functions always have an easy non-recurs开发者_运维技巧ive equivalent.
I am creating a factory that make开发者_开发技巧s rooms, and it is passed an int of steps and a start room and it is supposed to do a step, build a room, and then call itself with one fewer step and t
Some background first. I am currently learning some stuff about monadic parser combinators. While I tried to transfer the \'chainl1\' function from this paper (p. 16-17), I came up with this solution:
Here\'s my implementation of Sieve of Erathosthene in Clojure (based on SICP lesson on streams): (defn nats-from [n]
I write 开发者_Go百科some code to learning F#. Here is a example: let nextPrime list= let rec loop n=
Recently, I\'m learning F#. I try to solve problem in different ways. Like this: (* [0;1;2;3;4;5;6;7;8] -> [(0,1,2);(3,4,5);(6,7,8)]
I have some mutable scala code that I am trying to rewrite in a more functional style.It is a fairly intricate piece of code, so I am trying to refactor it in pieces.My first thought was this:
How do I break out a loop? var largest=0 for(i<-999 to 1 by -1) { for (j<-i to 1 by -1) { val product=i*j
