algorithm - All permutations of n numbers in depth first manner -

how can generate permutations (order matters) replacements , order matters set of n numbers, contain m elements in each combination? i don't want use more memory, generate combination, want use it. first, note if order matters , replacements allowed, have n options choose each element ( m of those) - , amount of choices have remains constant. this means have n*n*...*n = n^m possible combinations. to generate them, can use recursion: python code: (if don't know python, read pseudo code, it's pretty clear). def generateall(numbers, m, currentpermutation=[]): if m == 0: dosomething(currentpermutation) return x in numbers: currentpermutation.append(x) generateall(numbers, m-1, currentpermutation) currentpermutation.pop() for example, if define def dosomething(l): print str(l) and run generateall([1,2,3], 4) output print combinations repalcements, order matters, of size 4 [1,2,3]: [1, 1, ...

javascript - Wow + jquery + animate div shows on load and then appear again -

i using jquery + wow + animate appearing div animations on page. working except page not loading smoothly. divs should appear smoothly first appear on page load, hide , after appear animation. please check www.pester.rs , see problem, have tried nothing works. it loading order issue - first, browser downloads document , display it. later when loads entire javascript hides content provide nice animation. think it's affected internet connection speed. solution 1 : hide content css load hidden cons: if javascript crashes, content stay hidden solution 2 : place code @ end of body, before other scripts loaded (before other script tag) var wows = document.getelementsbyclassname('wow') (i = 0; < wows.length; i++){ wows[i].style.visibility ='hidden'; } it executed right after page loading before jquery , should fast enough. solution 3 : use inserted css file head of document suggested there http://robertnyman.com/2008/05/13/how-to-hide-and-sh...

Why are the types different in Java variable declarations? -

this question has answer here: arraylist or list declaration in java 10 answers what purpose of specifying different types on left , right side in java variable declarations? for example, code standard: list<string> l = new arraylist<>(); why don't: arraylist<string> l = new arraylist<>(); or object l = new arraylist<>(); // silly example shows 2 extremes this list<string> l = new arraylist<>(); allows instantiate types of list , arraylist or linkedlist of string . can use methods of list arraylist<string> l = new arraylist<>(); can instantiate arraylist of string . object l = new arraylist<>(); cannot use list methods.

c# - WCF and IIS performance spawning thousands of tasks using Task Parallel library -

my scenario: a user login triggers wcf-server kicks off 20 async-tasks . each separate task (named job in code) calling external soap-services. 1 000 simultaneous users logging in, means 20 000 async tasks. must call services in batches (due external limitations), fetch paged data - allowed in parallel. every 1 of 20 tasks spawns 10 tasks of own, mean 400 tasks per individual login - 400 000 tasks 1 000 simultaneous logins. my 2 questions: how impact our iis , server performance? understand tasks queued , run in parallell if possible - there limits on recommended number of tasks? am using right approach in creating these tasks? running async (except waitall )? see code below: create tasks each service called foreach (var job in jobs) { task.factory.startnew(() => job.fetch()); } the job-class called above: public async void fetch() { var batchlist = await fetchbatches(); //saves list database mergeandsavebatchlist(batchlist); } private async ...
