To my mind the power of functional purity is when deep code paths can be verified as side-effect free.What are people\'s experiences in the scale of the code tree that can be inside a pure specifier,
Supp开发者_运维问答ose I define a function globally: (defun x (y) (1+ y)) ;; Edit: my first example was too complicated
I have an unsorted list of rectangles (described as pair of lower left and upper right coordinates). I am looking for an efficient algorithm to compress this list by replacing neighboring or overlappi
Is it at all practical to implement an object model in functional style? One problem that OOP seems to excel at is describing object models.
I\'m looking at Functional Java and I don\'t understand what a P1 is. Could anyone explain and/or give an example?
I am new to lambda开发者_如何学C calculus and struggling to prove the following. SKK and II are beta equivalent.
I\'m currently doing a Functional Programming course and I\'m quite amused by the concept of higher-order functions and functions as first class citizens. However, I can\'t yet think of many practical
EDITED because question is about same program. I\'m trying to take the top fifty items in the first vector and write them to the topfifty variable, to return to use elsewhere.
This question already has answers here: Is it possible to modify a variable in python that is in an outer (enclosing), but not global, scope?
The normal approach to writing functions in R (as I understand) is to avoid side-effects and return a value from a function.
