when use "sieve of eratosthenes" generate prime number encountered problem. want create method takes in list , remove every 3rd list after 3: [2, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29...] -> [2, 3, 5, 7, 11, 13, 17, 19, 23, 25, 29...] .and here code: private static void removethird(list<long> l) { int = 1; int count = 0; while (i < l.size()) { // system.out.print(count + ":"); //debug // system.out.print(l.get(i) + " "); if (count == 3) { l.remove(i); count = 1; } ++; count ++; } } this code works, because want generate huge amount of prime numbers need long size list. therefore if want able access , modify each item in list need long type store index. changed int = 0 long = 0 , , code doesn't work. , viewed docs list class , realized can call list.remove(int index) . wonder if want call list.remove(long index) ? there way so? thanks! li

i have looked through discussion on what return type of boost::bind? , see short answer don't need know. while have function taking "bind(...) result" argument , find following difference behaviour working case 1 void func(int a){}; myfunc(bind(&obj::func,this,_1)); not working case 2 ( when want bind func2 2 argument) void func2(int a, int b){}; myfunc(bind(&obj::func2,this,_1,_2)); made working case 3 void func3(int a, int b){}; myfunc(bind(&obj::func3,this,_1, 10)); so question what's differnt on retrun type of following 3? bind(&obj::func,this,_1)); bind(&obj::func2,this,_1,10)); //why 1 can passed same type above one? bind(&obj::func3,this,_1,_2)); as myfunc quite embedded in template , overloading functions, didn't yet find how defined take "bind(...)" argument. that's why didn't attach code myfunc as answer linked says, don't need know exact return type.

i have 1 mini question select text in selected div. i have created demo codepen.io . in demo can see there 1 blue button , text in textarea. want when select select text. , click blue button selected text should <div class="selected">select text.</div> after clicking blue button. how can that. can me in regard ? $(document).ready(function() { $("body").on("click", ".bold", function() { // code goes here... }); }); html, body { width: 100%; height: 100%; padding: 0px; margin: 0px; font-family: helvetica, arial, sans-serif; -moz-osx-font-smoothing: grayscale; -webkit-font-smoothing: antialiased; background-color: #fafafa; } .container { position: relative; width: 100%; max-width: 500px; margin: 0px auto; margin-top: 30px; } .editor { float: left; width: 100%; padding: 30px; box-sizing: border-box; -webkit-box-sizing: border-box; } .editbuttons

i use sqlalchemy , there @ least 3 entities: engine , session , connection , have execute method, if e.g. want select records table can this engine.execute(select([table])).fetchall() and this connection.execute(select([table])).fetchall() and this session.execute(select([table])).fetchall() result same. as understand if use engine.execute creates connection , opens session (alchemy cares you) , executes query. there global difference between these 3 ways of performing such task? a one-line overview: the behavior of execute() same in cases, 3 different methods, in engine , connection , , session classes. what execute() : to understand behavior of execute() need executable class. executable superclass “statement” types of objects, including select(), delete(),update(), insert(), text() - in simplest words possible, executable sql expression construct supported in sqlalchemy. in cases execute() method takes sql text or constructed sql expre

the same code, run several times, different results. why following results not sorted? you put results dict – data structure not guarantee order of keys/values. seems you're aware of that, judging call sorted() . however, function doesn't work presume: rather modifying list (or iterable, in general), returns new one . documentation linked above states: return new sorted list items in iterable. and since result of function isn't assigned variable, perishes. alternately, result can used directly collection iterate on in for loop, this: for key in sorted(scores): print(scores[key] + ' had ' + key)

a guy learning php sent me code has me scratching head. he's getting $_post input, putting in variables, , then: if( !empty($id && $name && $email) ) { //do } my first inclination passing multiple variables argument throw error, evaluates successfully. incorrect empty() should not take boolean expression? or - if i'm right - why work? you can pass expression empty rather variable (since php 5.5), expression lose half of benefit of using empty . empty checks variables set evaluating "truthiness". when give expression that, individual variables within expression not checked exist empty . expression evaluated boolean. so if used separate empty checks, check variables exist check != false if(!empty($id) && !empty($name) && !empty($email)) but when use if (!empty($id && $name && $email)) you still if block if variables set , have non-false values, you'll undefined variable notices

okay im making app add items cart , updates add. adding fine, cant deleting work. in cart cell need remove 3 arrays, doesn't seem problem because keep getting error: "terminating app due uncaught exception 'nsinternalinconsistencyexception', reason: 'invalid update: invalid number of rows in section 0. number of rows contained in existing section after update (1) must equal number of rows contained in section before update (1), plus or minus number of rows inserted or deleted section (0 inserted, 1 deleted) , plus or minus number of rows moved or out of section (0 moved in, 0 moved out).'" i'm not sure i'm doing wrong here. i've followed few tutorials , seem doing same thing. appreciated in advance. heres of code: //declaring arrays show in cell var cartkeys = [string]() var cartvalues = [string]() var deets = [[string]]() var count = 0 //populating arrays original arrays func populatecart(){ (key,value) in menustore.s
