recursion

问题 Let's say that I have a few applications in a folder (each application has subfolders where plugins can be located): Clients Application A ... Application B ... Application C ... ... Some files in these applications have an Export-attribute applied, others don't. Now, I want to be able to load these plugins in some of these applications. Is there a proper way to let MEF search recursively in every subfolder of a specified folder? 回答1: No, you will need to recurse through the directories

问题 I have a homework problem which is really messing with me right now, and I could use some help in how to implement it in DrRacket. I do not wish for code, just guidance, as I am very new to DrRacket. The assignment is to implement this phrase: "If n = 0, return the empty tiling (list of tile structs). Otherwise, place a tromino (L-shaped domino) in the center of the chessboard so that it covers the three quadrants of the chessboard that have no missing tile in them, and tile each of the

问题 This question already has answers here : Closed 9 years ago . Possible Duplicate: Is recursion ever faster than looping? I was first trained to program seriously in C, about 15 years ago. My employer wanted highly optimized code for computationally difficult tasks. I remember being advised more than once to rewrite recursions as loops, even at the expensive of readability, in order to avoid "recursion overhead." As I understood it then, recursion overhead was the extra effort required to push

问题 I am currently developing a random maze generator that stores the maze in a 2-dimensional array called grid . This will then be used later on to generate a real 3D maze that the user can then walk through. After doing some research, I attempted to create this maze generator using the recursive division algorithm, however due to the nature of the format of the maze, this isn't really working for me. From what I understand, the recursive division method does not treat walls as cells . For

问题 I'm trying to create a tree component. But I dont know how insert a item recursively inside a tree. Each item its created dinamically and I would like instert/create an item/branch of the tree in each level. Problem is that when I cant insert items on level 3. For example, I have this code generated: [{ "id": 0, "active": false, "favorite": false, "level": 0, "title": "New Branch 0", "editable": false, "checkbox": false, "checkboxEnabled": false, "children": [] }, { "id": 1, "active": false,

问题 I according the answer from use recursion to draw the tree and use recursion try to draw a depth of 3 and 3 branches per(like picture one) but it print a strange answer (like picture three) Please tell me where is the problem.THANK YOU. picture one: picture two: I use for to draw the answer const tree = [ [0, 0, 0 ], // A // root [-2, 104, -4 ], //B [-39, 189, -23],//c [-4, 230, 19 ], //D [34, 192, -61 ], //E [-150, 270, -72], //F [-115, 296, -63], //G [-106, 326, 6], //G [-82, 365, 23 ],//I
