how can rewrite following program in order not use loop , branch constructs? (no if, while, break, continue, switch, ...) for(int i=0; < 5; i++){ // stuff } the approach can think of use ugly goto statements: loop: // stuff goto loop; but how can exit loop after 5 runs? or there different way? edit: solution should not recursive. function calls not yet allowed in course. you can use recursive function , pass argument counter. decrease counter each time before calling. int func(int a,int counter) { int c; // .. logic return counter==0?a:func(a,counter-1); } this line return counter==0?a:func(a,counter-1); helps handling condition when counter==0 without using if.

my ios app downloading encrypted mp4 file server document folder. i'll decrypt mp4 memory , play video memory. for security, app should not make decrypted mp4 file doc folder. how can play video memorystream? i'm trying ffmpeg..or there other solutions? can customize avio_open2() , avformat_open_input()? please me.... set avformatcontext->pb self-created aviocontext wraps memory stream. important read_packet() , seek() function callbacks, application should implement actual packet reading , seeking (mp4) demuxer. can @ earlier questions along same path.

i studying queue-based approach bellman-ford algorithm for single source shortest path robert sedgewick , kevin wayne - algorithms, 4th edition source code algorithm book present @ link http://algs4.cs.princeton.edu/44sp/bellmanfordsp.java . i have 2 points 1 doubt , other code improvement suggestion. in above approach following code relax method relaxing distance vertices. for (directededge e : g.adj(v)) { int w = e.to(); if (distto[w] > distto[v] + e.weight()) { distto[w] = distto[v] + e.weight(); edgeto[w] = e; if (!onqueue[w]) { queue.enqueue(w); onqueue[w] = true; } } if (cost++ % g.v() == 0){ findnegativecycle(); } } in method below condition used before finding negative cycle. if (cost++ % g.v() == 0){ findnegativecycle(); } above dividing cost number of vertices in graph check negative cycle . may because relaxation done v-1 times , if relaxation run vth time mea...

i'm building mvc web application using spring-security securing app , angular.js clent side framework. ui.router changes content of page depanding on selected state. problem starts when user tries select page referring page lacks privilages access, spring returns login page, , ui.router inserts login page body of page. what do, redirect login page if login required instead of inserting current page. how can acheive that? i created 2 different angular modules, , each module had own routing. the 2 angular modules are: 1) loginmodule (with own ui-router configuration, es. login, retrieve password, forgot password , on...) 2) securedmodule: authenticated part i created 2 main pages entry point each ui-router /signin -> signin.html -> (loginmodule) -> ui-routing login /secured -> secured.html -> (securedmodule) -> ui-routing secure now can configure un spring configuration , assign /signin login page , path /secured authentic...

i've tried add jmx spark executors "spark.driver.extrajavaoptions". i've put --conf "spark.executor.extrajavaoptions=\"my options\"" in sumbit file, started job, verified if configuration visible on webui. have verified jmx netstat -an , there no listening on port have specified. have put same options in spark-defaults.conf , works fine. what doing wrong? i tried --conf "\"spark.executor.extrajavaoptions=my options\"" same effect. try \\ instead of \ might work. check if setting configurations using .setconf() method on spark context in code solves problem.

i have rough understanding of why = null in sql , is null not same, questions this one . but then, why is update table set column = null a valid sql statement (at least in oracle)? from answer , know null can seen "unknown" , therefore , sql-statement where column = null "should" return rows, because value of column no longer an unknown value. set null explicitly ;) where wrong/ not understand? so, if question maybe unclear: why = null valid in set clause, not in where clause of sql statement? sql doesn't have different graphical signs assignment , equality operators languages such c or java have. in such languages, = assignment operator , while == equality operator . in sql, = used both cases, , interpreted contextually. in where clause, = acts equality operator (similar == in c). i.e., checks if both operands equal, , returns true if are. mentioned, null not value - it's lack of value. therefore, cannot equal ...

is there way in sdsf mimic direct z/os console autorefresh and autoscroll down end of log? figured out can autoupdate &<time> , doesn't scroll down end of log gets updated. ideas? lol! easy. had use bot &<time> example: bot &5 . bot scrolling bottom of log , &<time> so command gets repeated in 5 sec interval.

the main idea have string, no defined length (dynamic), , need group multiple columns (like in image example, ignore image part) . so, can see has precise. main idea have split string intro array of words, append each word container , check if text container fits parent container (that fixed). although idea might work, seems overkill, so, have better idea on how handle this? cannot use css property makes this, has done strictly js, because have further group text images in columns. just clear, don't have 3 columns, dynamic, can have 1 4 columns. if don't need support ie < 10, simpler: http://www.w3schools.com/css/css3_multiple_columns.asp

i'd include small logo in footer on every page on pdf version of book not on html version. is possible? pointers on how might achieve this? i'm using git book version 2.0.1 thanks million. ct as far know not possible add logo pdf , not html version. i think 1 possibility achieve goal make second html version. first 1 gitbook, second 1 copy of first one, logo @ end of each page. can convert second 1 pdf. another possibility search watermark tool pdf files , add logo way. sadly both ways additional expenses, see no other way

so had field issue, , after days of debugging, narrowed down problem particular bit of code, processing in while loop wasn't happening : // heavily redacted code // numbera , numberb both of uint16_t // important stuff happens in while loop while ( numbera + 1 == numberb ) { // processing } this had run fine, until hit uint16 limit of 65535. bunch of print statements later, discovered numbera + 1 had value of 65536 , while numberb wrapped 0 . failed check , no processing done. this got me curious, put quick c program (compiled gcc 4.9.2) check this: #include <stdio.h> #include <stdint.h> int main() { uint16_t numbera, numberb; numbera = 65535; numberb = numbera + 1; uint32_t numberc, numberd; numberc = 4294967295; numberd = numberc + 1; printf("numbera = %d\n", numbera + 1); printf("numberb = %d\n", numberb); printf("numberc = %d\n", numberc + 1); printf("numberd = %d\n...

i'm running cmd.exe .net program using process class , passing in various commands execute programs i.e. ipconfig, netstat etc. issue these programs output error text, sent standarderror, there no way of knowing during standard output error printed. error message separately. possible combine standardoutput , standarderror 1 synchronized stream data in order? if not, how organize output 2 different streams it's in proper order? well. guess can't expect stdout , stderr come in exact order have been output. because @ system level, stdout , stderr have own buffer respectively. can imagine such case - (1) when 'command' writes stdout first, buffer might not flushed immediately. (2) 'command' writes stderr, however, time buffer stderr might flushed. in case, though (1) comes first, (2) comes first. hope following snippet - (improved code) class outputcontext { public const int buffersize = 1024; public bool iseof {...

for api need have md5 result routes, use: server.ext('onpreresponse', function(request, reply) { var content = request.response.source; var code = request.response.statuscode; if(typeof request.headers.md5 != 'undefined' && code == 200) { content = md5(content); } if(!debug && code != 200){ content = "error"; } reply(content).code(code); }); when response 404 error, request.response doesn't have response.statuscode ... can handle with: if(typeof code == 'undefined'){ code = 404; } but when try view documentation generated lout, have this: how can forward code message? you want use reply.continue() rather reply().code() a similar question answered here: https://github.com/hapijs/discuss/issues/103
