this asked in on-site microsoft interview. count number of occurrences of given key in array. i answered linear search because elements may scattered in array. key found in beginning , @ end. need scan entire array. next asked if array sorted? thought while , said i'll use linear search again. because repetitions of key if present can anywhere in array. optimization said if first , last array elements same can take array length answer. is analysis correct in both cases? example: input = [0 0 1 1 1 2 2 3 3], key = 1, answer = 3 input = [0 0 2 2 3 3], key = 1, answer = 0 for unsorted array there not can other linear search. for sorted array can in o(logn) using modified binary search: find index of first occurrence of key , call f . find index of last occurrence of key , call l . if key exists in array l-f+1 answer. finding first occurrence: arr[i] first occurrence of key iff arr[i] == key and either i == 0 ( it's first el

what mean this: scala> class bounded[t <: string](val t: t) defined class bounded scala> val b: bounded[_] = new bounded("some string") b: bounded[_] = bounded@2b0a141e scala> b.t res0: = string why res0 have type , not string? sure know b.t @ least string. writing val b: bounded[_ <: string] = new bounded("some string") works, redundant respect declaration of class itself. first, have edited question title. not using dependent types, scala doesn't have anyway, existential types. second, not inferring anything, explicitly declaring type. now, if did write bounded[any] , scala wouldn't let you. however, 1 of uses of existential types deal situations type parameter unknown -- such java raw types, where. so guess making exception in situation seems obvious enough break other situation existential type way deal something.

i know how updates work apple store. does apple delete old data related old version of application , update newer one? when user updates new version of application, older version deleted iphone data ( pictures, database, sound,etc) , replaced newer version or not? i updated application few days ago, , think apple not replace old sqlite database newer one. during update old application bundle replaced new one. other folders , contents in application sandbox (documents, library, tmp) remain untouched. so if want replace old database (if must save data changed users in old database) need check database version in app , copy new 1 application bundle if version old (you can use sqlite user_version pragma version tracking)

i developing enterprise app has lot of dynamic content. there way have app auto update content(new stories, download new videos, etc) @ 3am every sunday. is possible? while it’s not possible when app isn’t running, can @ launch or while running (if it’s going running @ 3 am). here’s i’d do: store nsdate using nsuserdefaults last time updated. at launch, if 3 period has passed since date, initiate sync. also @ launch, start nstimer long interval—5 minutes or so. @ each firing, check if 3 period has passed , if has, initiate sync. roll last bullet’s code nstimer ’s firing method , run once @ launch. sure update nsdate object each time. in application delegate, in methods called returning background, check time , sync if necessary—or start nstimer , have fire first. that should cover of scenarios need update app.

i have declared stored procedure in sybase, , 1 of parameters of type datetime. want assign datetime default value. here's declaration: create procedure procedure ( @fromdate datetime = getdate() ) ... however sybase giving me error number (102) severity (15) state (1) server (server) procedure (procedure) incorrect syntax near '('. is possible this? if not, there workaround? you can not use function call in default variable assignment (as found out). set default null, , put assignment first thing in stored procedure. create procedure procedure ( @fromdate datetime = null ) begin set @fromdate = coalesce( @fromdate , getdate() ) end

mysql select * media left join media_priority on (media_priority.media_id = media.id , media_priority.media_tag = '".$tag."') = 'something' order media_priority.media_order; this works fine except media_priority.media_order comes null , mysql puts null values @ top. so trying figure out how null tempcol statement left join can order first.....i can't seem syntax right. where put null statement in query above? i thinking like: left join media_priority on (media_priority.media_id = media.id , media_priority.media_tag = '".$tag."') media_priority.media_order null isnull but doesn't work. order case when media_priority.media_order null 1 else 0 end, media_priority.media_order; or use magic number if have upper limit media_order never feasibly reach. order coalesce( media_priority.media_order,99999999); the first approach safer!

i testing code asynchronous processing using grand central dispatch. testing code looks this: [object runsomelongoperationanddo:^{ stassert… }]; the tests have wait operation finish. current solution looks this: __block bool finished = no; [object runsomelongoperationanddo:^{ stassert… finished = yes; }]; while (!finished); which looks bit crude, know better way? expose queue , block calling dispatch_sync : [object runsomelongoperationanddo:^{ stassert… }]; dispatch_sync(object.queue, ^{}); …but that’s maybe exposing on object . trying using dispatch_sempahore . should this: dispatch_semaphore_t sema = dispatch_semaphore_create(0); [object runsomelongoperationanddo:^{ stassert… dispatch_semaphore_signal(sema); }]; dispatch_semaphore_wait(sema, dispatch_time_forever); dispatch_release(sema); this should behave correctly if runsomelongoperationanddo: decides operation isn't long enough merit threading , runs synchronously inste

greetings, new haskell , i've gotten stuck in defining datatype assignment. i need create "strategy" type, it's string 1-6 characters each representing numeric value, , must represent values greater 9 letter (up 35 total different values), tried defining auxiliary type representing each possible value , using create type, code isn't working , have ran out of ideas. definition have been trying: data value = '1' | '2' | '3' | '4' | '5' | '6' | '7' | '8' | '9' | 'a' | 'b' | 'c' | 'd' | 'e' | 'f' | 'g' | 'i' |'j' | 'k' | 'l' | 'm' | 'n' | 'o' | 'p' | 'q' |'r' | 's' | 't' | 'u' | 'v' | 'w' | 'y' | 'x' | 'z' data strategy = value | value:value | value:value:value | value:value:value:value |

take f# following code: type blah<'t>(objects : 't array) = // whatever when try use type in xaml document, there no type associated generic parameter, , it's ugly. think compiler complains, too: <ns:blah foo="bar"/> so, try alias type (at bottom of blah.fs file): type stuffblah = blah<stuff> then when use in same way in xaml document, type not found exist: <ns:stuffblah foo="bar"/> why that? there cleaner, more elegant way this? i'm still getting hang of silverlight, xaml, , f#, advice appreciated. thanks. the reason stuffblah version doesn't work particular piece of f# syntax creates type alias f# project vs. creating actual type. since name not visible @ il level actual type not accessible silverlight or xaml in general. one way work around create stuffblah first class type derives stuff<'t> . not ideal @ work.

there have been hundreds if not thousands of posts concerning use of php's eval(); run code database. through searching have not found answer question (explained shortly). firstly i'll introduce application. i have 3 records of valid code stored in database: eg: ['code1'] $num1 = 1; $num2 = 3; $num3 = $num1+$num2; //4 ['code2'] $num4 = $num3; //4 $num5 = 5; $num6 = $num4+$num5; //9 ['code3'] $num7 = $num4; //4 $num8 = $num6; //9 $num9 = $num7+$num8; //13 echo $num9; //13 next have function call , run record: eg: function runcode($codename) { // assume db connection established $result = mysql_query("select `code` codestore `name` = '".$codename."'"); if ($result) { // fetch 1 row $row = mysql_fetch_assoc($result); if (!$row) { die('no rows returned.'); } else { return eval($row['code'])

i'm new java, i'm sorry if answer seems obvious... i've written method in class follows: private static final string[] rcode = {"m", "cm", "d", "cd", "c", "xc", "l", "xl", "x", "ix", "v", "iv", "i"} private int getcharvalue(string code) { // loop through codes find // matching code, if found exit loop (via return). (int position = 0; position < rcode.length; position++) { if (rcode[position] == code) return rval[position]; } // // otherwise return 0 return 0; } // getcharvalue in method of same class looping through characters of string follows: string number = "mmmcdxxxiv"; (int pos = 0; pos < number.length(); pos++) { system.out.println(number.substring(pos, pos + 1) + " " + getcharvalue(number.substring(pos, pos + 1))); } // my problem while getcharva

an upgrade app went live in itunes. 3gs iphones seem having issue if 3gs did upgrade of app. if 3gs iphone fresh download or deletes app , downloads it, fine. i'm wondering if have missed coding perspective should have prevented issue? i used several 3gs iphone testers. same 3gs iphones tested adhoc fine, have upgrade issue. iphone 4s have no issues whether downloads new or upgrades. is there chance upgrade not replacing previous version of there app? is there xcode setting ensure such thing? or kind of fluke? i have upgraded other apps in past similar functionality , had no issues. did had breaking changes in app data formats? if remember correctly, itunes upgrades backup app data on device , restores after upgrade.

we're building mobile application, , we're evaluating nhibernate + fluent use it. problem is, first time create isessionfactory, takes full 2 minutes. though table structure simple (3 tables). each call after extremely fast. what i'd either cache isessionfactory between application restarts, or somehow speed creation of in first place. any ideas on if it's possible cache? reading, there's not speeding up. you can serialize , save configuration , load second time around reduce time takes create. tho if make changes need blow away old config , serialize new version, otherwise loading old configuration. i can't remember code tho, try dig example. edit: http://vimeo.com/16225792 in video @ 24 minutes in ayende discusses configuration serialization.

using latest cakephp build 1.3.6. i'm writing custom datasource external rest api. i've got read functionality working beautifully. i'm struggling model::save & model::create. according documentation, below methods must implemented (see below , notice not mention calculate). these implemented. however, getting "fatal error: call undefined method apisource::calculate()". implemented apisource::calculate() method. describe($model) listsources() @ least 1 of: create($model, $fields = array(), $values = array()) read($model, $querydata = array()) update($model, $fields = array(), $values = array()) delete($model, $id = null) public function calculate(&$model, $func, $params = array()) { pr($model->data); // post data pr($func); // count pr($params); // empty return '__'.$func; // returning __count; } if make call model $this->save($this->data) it calling calculate, none of other implemented met

im having few problems form_dropdown function in codeigniter .... application in 2 parts, user goes in, enters form , submits .... once submitted admin can go in , edit persons form , save database. so, display dropdown in initial form, im using following ( options in dropdown coming database ) model: function get_salaries_dropdown() { $this->db->from($this->table_name); $this->db->order_by('id'); $result = $this->db->get(); $return = array(); if($result->num_rows() > 0){ $return[''] = 'please select'; foreach($result->result_array() $row){ $return[$row['id']] = $row['salaryrange']; } } return $return; } then in controller: $data['salaries'] = $this->salary_expectation->get_salaries_dropdown(); then view: <?php echo form_dropdown('salaries', $salaries, set_value('salaries', $salaries)); ?>

i using c++.net , program needs make directory i system command system("mkdir"); but when command in gui program cmd window comes in , disapears again there way command without window showing up? or there easier way make directory in c++? thanks luck createdirectory ( http://msdn.microsoft.com/en-us/library/aa363855%28vs.85%29.aspx ) easier way, though have create intermediate directories yourself. alternatively can use createprocess launch console flag create_no_window (and remember wait process terminate).

a measured value consists of (typically nonnegative) floating-point number , unit-of-measure. point represent real-world quantities, , rules govern them. here's example: scala> val oneinch = measure(1.0, inch) oneinch : measure[inch] = measure(1.0) scala> val twoinch = measure(2.0, inch) twoinch : measure[inch] = measure(2.0) scala> val onecm = measure(1.0, cm) onecm : measure[cm] = measure(1.0) scala> oneinch + twoinch res1: measure[inch] = measure(3.0) scala> oneinch + onecm res2: measure[inch] = measure(1.787401575) scala> onecm * onecm res3: measure[cmsq] = measure(1.0) scala> onecm * oneinch res4: measure[cmsq] = measure(2.54) scala> oncem * measure(1.0, liter) console>:7: error: conformance mismatch scala> oneinch * 2 == twoinch res5: boolean = true before excited, haven't implemented this, dummied repl session. i'm not sure of syntax, want able handle things adding measured quantities (even mixed units), multiplying measured q

typically like: q = queue() p = process(target=f, args=(q,)) p.start() is there way pass p queue? er... think - can done through q? yes, can done via q . can pass object there, queue included i wouldn't recommend practice, however. describe why need this, maybe there's better design.
