@dfeuer 这并不是为了展示一个更简单的例子,而是为OP提出一个合适的练习,并暴露出解决方案的合理论证,试图证明不必成为超级 Haskell 大师也能得到这样的解决方案。关于效率的离题讨论不予考虑。 - lsmor 3 你不需要具备数学方面的专业知识才能编写像 foldM 这样的函数。我已经在生产环境中使用 Haskell 4 年了,...
不使用higher-order functions并且不约束求值策略和顺序的。 不使用higher-order functions并且精确约束约束求值策略和顺序的。 使用higher-order functions并且精确约束约束求值策略和顺序的。 说起来似乎很复杂,但是消除higher-order functions和约束求值策略在当今这个时代其实已经被广发地应用于现代编译器之中了,他们就是两...
For the rapid development of internetware, functional programming languages, such as Haskell and Scala, can be used to implement complex domain-specific applications. In functional programming languages, a higher-order function is a function that takes functions as parameters or returns a function. ...
We introduced user-defined functions as a mechanism for abstracting patterns of numerical operations so as to make them independent of the particular numbers involved. With higher-order functions, we begin to see a more powerful kind of abstraction: some functions express general methods of computatio...
Bend offers the feel and features of expressive languages like Python and Haskell. This includes fast object allocations, full support for higher-order functions with closures, unrestricted recursion, and even continuations. Bend scales like CUDA, it runs on massively parallel hardware like GPUs, ...
python入门编程, 之后用c++学习数据结构,Haskell萌新。 由于对Haskell中一些词语的中文翻译并不了解,接下来的内容中重点名词将有英文和我理解的中文。 Chapter5主要内容 调制函数(curried function) 在前面学习的函数里,我们理解的函数通常接受一个或多个参数(parameter),并返回对应的结果,而这个结果也通常以参数的形式...
range-free LINQ-like library of higher-order functions for manipulation of containers and lazy input-sequences. Documentation What it's for Reduce the amount of mutable state. Flatten control-flow. Lessen the need to deal with iterators directly. ...
That is, we often want to consider each node in the context of the entire graph we started with. In order to express that withfold, we have to decompose the original graph at each step: 1234567 defmaxDegree[V,N,E](g:Graph[V,N,E]):Int=g.fold(0){(c,z)=>g.decompose(c.vertex...
Flow analysis of lazy higher-order functional programs In recent years much interest has been shown in a class of functional languages including HASKELL, lazy ML, SASL/KRC/MIRANDA, ALFL, ORWELL, and PONDER. It ... ND Jones,N Andersen - 《Theoretical Computer Science》 被引量: 113发表: 200...
