this program takes array of n length, , uses heapsort pull smallest k elements out. have gotten k number smallest elements out of array, have been trying several hours them print in ascending order. complete binary tree building correctly, based upon father > son. if me figure out need appreciate it. also, homework assignment , i'm not asking code fix it. legitimately stumped, , set on correct path working correctly. in advance input. edit - kind of have output in ascending order, basic test getting: 5,6,31,34,29, import java.lang.*; import java.util.*; public class heap { /* * definitions of parameters * 1) tree: array sweeping window implemented * 2) newele: new element insert * 3) pos: insert new element initially. * note not mean newele going * stay @ pos after function * 4) increment * a) true: insert newele, * b) false: insert newele , remove root */ static void insertheaptreeat(int[] tree, int newele, ...

so insert statement works perfectly. know database connecting because can select information database first 2 statements. know execute_statment3 works because no errors being printed off , when put sql statement inserted way should be. therefore problem lies somewhere communication between script , phpmyadmin. please have been staring @ problem 2 days , going rather crazy. <?php session_start(); $hostname = 'localhost'; $username = '####'; $password = '####'; $connection = mysql_connect($hostname, $username, $password) or die ('connection error!!!'); $database = '####'; mysql_select_db($database); $uid = $_session['id']; $album = $_post['albumname']; $description = $_post['description']; $filename = $_files["upload_file"]["name"]; $filetype = $_files["upload_file"]["type"]; $filesize = $_files["upload_file"]["size"]; $file_on_server = $...

in emacs, when ssh'ed remote machine, there's delay between when type closing quotation mark , when emacs updates syntax-highlighting reflect change. few seconds, of text after quotation highlighted if part of quotation. fine, i'd rather not wait. there way tell emacs "re-highlight right now"? yes. emacs command m-x font-lock-fontify-buffer if recall right. can bind key sequence if it's not bound in mode.

this question has answer here: what “best” way , set single cookie value using javascript 3 answers i trying implement cookies on page; having trouble getting function properly. wanting store value of variables well. realize broad, know little nothing jscript cookies , working off w3schools examples. if has helpful insight push me along great. have far: var days=365; function setcookie(child,user,days) { var exdate=new date(); exdate.setdate(exdate.getdate() + days); var child=escape(user) + ((365==null) ? "" : "; expires="+exdate.toutcstring()); document.cookie=child + "=" + child; } function getcookie(child) { var i,x,y,arrcookies=document.cookie.split(";"); (i=0;i<arrcookies.length;i++) { x=arrcookies[i].substr(0,arrcookies[i].indexof("=")); y=arrcookies[i].substr(arrcookies[i].indexof("=")+...

i have bitmap 2 large blocks of colors intersect, , find intersection of these 2 blocks. note not know actual geometry of 2 shapes, because raw pixel data. is there algorithm use this? if have pixel data in memory (which i'd assume do, major sticking point) , there 2 distinct colours, should need run horizontal scanline find point rgb changes colour x colour y (note may need run scanline few times, in case it's no worse o(height)). simple graph traversal (bfs or dfs) continue walk down line (you should need 3 points , you'll able form geometric line equation a*x + b*y + c = 0 (assuming it's not curve)). repeat scanline vertically (again, worst case it's o(width)). find 3 points , you'll have 2 lines d*x + e*y + f = 0. using little bit of comp. geom, intersection of these 2 lines give point.

this first time using push notification in app.i have gone through sample applications along books , got how send push notification single device.but not getting changes should in program send push notification multiple devices.i using 'pushmebaby' application server side coding. please,help me out. in advance. try example code , modify environment. $apnshost = '<apns host>'; $apnsport = <port num>; $apnscert = '<cert>'; $streamcontext = stream_context_create(); stream_context_set_option($streamcontext, 'ssl', 'local_cert', $apnscert); $apns = stream_socket_client('ssl://' . $apnshost .

i have program: import java.util.*; public class test { private string s; public test(string s) { this.s = s; } public static void main(string[] args) { hashset<object> hs = new hashset<object>(); test ws1 = new test("foo"); test ws2 = new test("foo"); string s1 = new string("foo"); string s2 = new string("foo"); hs.add(ws1); hs.add(ws2); hs.add(s1); hs.add(s2); // removing line gives same output. system.out.println(hs.size()); } } note not homework. asked question on our quiz earlier today. know answers trying understand why so. the above program gives 3 output. can please explain why is? i think (not sure): the java.lang.string class overrides hashcode method java.lang.object . string objects value "foo" treated duplicates. test class not override hashcode method , ends using java.lang.object version , ...

int num1, num2,num3,num4, i=0; nsmutablearray *chararray = [[nsmutablearray alloc] init]; while(num1 != 0 && num2 != 0) { num3 = num1 & 1; num4 = num2 & 1; if(num3 != num4) { if(num3 == 0) { chararray[i++]= '0'; chararray[i++]= '1'; } else { chararray[i++]='1'; chararray[i++]='0'; } } num1 = num1 > 1; num2 = num2 > 1; } } i kinda new objective-c, can tell me whats wrong this? you can't use regular array-like subscripts nsarrays (and nsmutablearrays). add item, need call addobject method.. i.e. [chararray addobject:obj] . the other caveat can't add bare char nsarray, needs objective-c type. can use nsnumber class wrap it. code be: [chararray addobject:[nsnumber numberwithchar:'0']]; [chararray addobject:[nsnumber numberwithchar:'1']]; but can still use regular c array , leave code unmodified, better solution in case. i.e. char c...

i have 2 versions of function available in c++ library same task. 1 synchronous function, , of asynchronous type allows callback function registered. which of below strategies preferable giving better memory , performance optimization? call synchronous function in worker thread, , use mutex synchronization wait until result do not create thread, call asynchronous version , result in callback i aware worker thread creation in option 1 cause more overhead. wanting know issues related overhead caused thread synchronization objects, , how compares overhead caused asynchronous call. asynchronous version of function internally spin off thread , use synchronization object, or uses other technique directly talk kernel? "profile, don't speculate." (djb) the answer question depends on many things, , there no general answer. role of developer able make these decisions. if don't know, try options , measure. in many cases, difference won't matter , non...

insert ellipsis (...) html tag if content wide mentions how insert ellipsis html content. solution works, find when applied large dataset (imagine 1,000 div's) tends pretty slow. my jsfiddle demonstrates issue. changing variable set (numberofdivs) 10 100 dramatically increases time takes output results. changing number 100 1000, causes chrome want kill page. it seems jquery's solution, , others have seen, involve either populating element in dom text (i believe jquery plugin used of sort, seems expensive large datasets) or using feature not supported ie7 , other older browsers (text-wrap:ellipsis). it seems calls element.offsetwidth or element.clientwidth expensive when dealing large sets of data. has found optimizations or robust server-side solutions? when robust server-side solution, mean 1 takes account text's size , size of containing div (or other element). doing substring of text 1 solution, not consider robust. nobody have found robust ...

i know if jquery 1.5.x has cross-domain. unable find sufficient documentation on site , own cross-domain tests did not work either. not talking jsonp regular call (xml, html, json). i not see how jquery can circumvent browser restrictions without use of adobe flash/proxy etc. if browser supports cors can directly use jquery's ajax methods send cross-domain ajax request. unfortunately ie uses different method not supported jquery (yet?).

i want create app in have these 2 classes, mainapp , model (in reality more, base , core of problem). mainapp starting class. want apply dependency inversion mainapp doesn't have rebuild each time model changes (well, because practice). can't this: mainapp - - - > imodel ^ | | model because i'd have create model in mainapp anyway because it's start of app, redundant. i thinking shifting contents of mainapp class , use mainapp factory mainappcontents , model, this: mainapp -------------> model | | | | v v mainappcontents - - - > imodel is correct approach , mean start of designed app factory? it sounds asking way enable late binding . programming interface first step, , doing that. the next step map interface concrete class . easiest way di container . main method might this: static void main() {...
