this question: a dosod number divisor of sum of digits. example, if take number 12, sum of digits 1 + 2 = 3. 12 divisible 3 , hence dosod number. same reasoning, 11 not dosod number, closest dosod number 11 12. write program take integer n input , print dosod number closest not less n. sample input-1 16 expected output 18 sample input-2 20 expected output 20 this code: class dosod{ public static void main(string args[]){ scanner s=new scanner(system.in); int n=s.nextint(); int temp=0,x; x=n; int y=n; while(n>0){ x=n%10; temp+=x; n=n/10; } if(y%temp==0){ system.out.print(y); }else if(y%temp!=0){ y=y+2; system.out.println(y); } } } but not passing test case .can ? you need update else branch. closest number forward or backward current number. since problem statement explicitly says closest...

i forked repo on github , wanted build project. figured jitpack easiest way this. followed instructions , still cannot compile. i noticed in android studio when expand "external libraries" section in left pane can see repo there. however, when expand it, not of classes there. there seem obfuscated. see java package name expect, see a, b, c, d, e, f, g, h, i, j, classes. in world going on here? i think know might happening here. android library forked had proguard enabled. think trying compile against binary built proguard via jitpack, don't think work. when build against github source through jcenter, guessing building source, , not compiled binaries why problem did not exist until started using jitpack , forked repo. not 100% sure however. i won't mark answer accepted until sure issue.

this question similar question: what difference between web sockets, long polling, server-sent events , forever frame? however, question's answer doesn't mention difference between sse , forever-frame. let me give brief explanation them. regarding sse, system resembles comet, point different comet not breaking connection after data being sent. so, connection server client long-alive , client receives series of fragments of whole data. on other hand, forever frame seems similar me. in forever frame, first client receives page including iframe tag, establishing long-lived connection inside hidden iframe. , client receives chunked datas server , manipulates dom functions on first document client has. i assume difference forever-frame uses iframe tag in mechanism, sse doesn't , sse can realized more ways. right? i'd not heard of forever-frame name before! (it covered in ch.7 of book, data push apps html5 sse, in "iframe" section). long-pol...

i trying understand , apply solid principles. regarding dependency inversion principle, means composition/aggregation object forbidden? interface must used access class method? i mean that: class serviceclass { void serviceclasshelper(); } class mainclass { void mainclass(serviceclass service); // use serviceclasshelper } must changed to: class serviceinterface { virtual void interfacehelper() =0; } class serviceclass : public serviceinterface { void serviceclasshelper(); void interfacehelper() { serviceclasshelper(); }; } class mainclass { void mainclass(serviceinterface service); // uses interfacehelper } i think (or @ least hope) understand principle. wonder if can rephrased that. indeed, stuff read dip suggest use interfaces. thanks! basically, main idea of dip is: high-level modules should not depend on low-level modules. both should depend on abstractions. abstractions should not depend on details. details should depend on ...
