问题 I have data with 'from' and 'to' columns: df = data.frame(from = c('A','A','X','E','B','W','C','Y'), to = c('B','E','Y','C','A','X','A','W')) I'd like to identify all sequences of 'from-to', considering two or more rows, which starts and ends on the same value. An easy one would be A-B-A : # df # from to # 1 A B # 1. From A to B # 2 A E # 3 X Y # 4 E C # 5 B A # 2. From B and back to the starting point A, completing the sequence A-B-A # 6 W X # 7 C A # 8 Y W Another one: # df # from to # 1 A

问题 Are there any nice ways to use while and repeat loops in Twig? It is such a simple task, but without macros I can't find anything nice and simple. At least do an infinite cycle and then break it in a condition? EDIT: I mean something like do { // loop code } while (condition) or while (condition) { // loop code } Edit 2: Looks like it is not supported natively by twig same reason as it is not supported neither continue; or break; statements. https://github.com/twigphp/Twig/issues/654 回答1: In

问题 In my nested slideshows I have 'prev' and 'next' controls. I would like to be able to reduce the css opacity of 'prev' if you are on the first slide and 'next' if you are on the last slide. The 'after: onAfter' option would have been sufficient but it didn't appear to work when placed in my code for the nested slideshow controls. Is there a way to implement 'after' correctly in a nested slideshow, or alternatively test for first and last images in the nested slideshow? Thankyou Here is my

问题 To be Google friendly, I want to change this script a little bit. I have a one page layout, where I use jQuery Cycle to animate between content. The script, as it is now, displays the current slide's number in the URL. Ex. "index.html#1" or "index.html#4". It looks horrible and I think Google would think too... ;-) I want it to display the divs #anchor instead of its index, so the url would be "index.html#Projects" instead The HTML menu: <div id="menu"> <ul> <li><a href="#About">About</a></li

问题 My program is caught in a cycle that never ends, and I can't see how it get into this trap, or how to avoid it. It's parsing Wikipedia data and I think it's just following a connected component around and around. Maybe I can store the pages I've visited already in a set and if a page is in that set I won't go back to it? This is my project, its quite small, only three short classes. This is a link to the data it generates, I stopped it short, otherwise it would have gone on and on. This is

问题 I know that python is a crazy language because of it's cycles constructions :) So, I have an array of numbers but in string type: a = ['1', '40', '356', '...'] I need this or a copy of this array but with float type instead of string. The only thing is that the code should be in one line. Help me, please :) 回答1: You can use map()[docs] and float()[docs]: b = map(float, a) 回答2: a = ['1', '40', '356', '...'] b = [float(x) for x in a] This is called a list comprehension. It's a very powerful

问题 This is driving me crazy. Like these people, slow-android-emulator, I'm finding running the emulator from eclipse is slow and problematic. As suggested, I've tried running the emulator seperately. But then I don't get my latest changes. I don't know eclipse that well, but I would like something like 'build' and then somehow load the latest image into the emulator. Also, I've tried keeping the emulator open and the continually use run->debug, but after 2 or 3 times, I get errors like the

问题 I have a weighted directed multigraph with a few cycles. With clusters function in igraph package, I can get the nodes belongs to a strongly connected components. But I need the path/order of the nodes that form a cycle. EDIT after @josilber's response I have a very dense graph, with 30 nodes and around 2000 edges. So graph.get.subisomorphisms.vf2 takes too long to run in my case. I'm not familiar with graph algorithm, but I'm thinking maybe do a DFS to the original or reverse graph and use
