let me expose question: have main script, let's creates instance of "game" object, which, depending on actions of user, loads 1 of many javascript files, let's call them "levels" :d these files contains different objects, example, "level1.js" contains object level1, "level2.js", etc. each time level script loaded, example level1.js, instance of "game" creates instance of object level1 , stores in local variable. the way i've found it, write, @ end of "level" scripts, global variable, has same name, , points definition of current level. in game, when level script loaded, use global variable create instance of current level. know if there way without using global variable. here simplified example: in game.js: function game() { var levelcurrent = null; var scriptcour = document.createelement("script"); scriptcur.type = "text/javascript"; scriptcur.onload = function() ...

hi there trying solve following recurrence relation telescoping stuck on last step. t(n) = t(n/2) + n t(1)=0 t(n/2) = t(n/4) + n/2 t(n/4) = t(n/8) + n/4 ... t(2) = t(1) + 2 t(n)= t(1) + n + n/2 + n/4 i think answer nlogn don't know how interpret above nlogn. can see doing logn steps n come from? you have done absolutely correctly, not able find sum. got: n + n/2 + n/4 + ... , equal n * (1 + 1/2 + 1/4 + ...) . you got sum of geometric series , equal 2 . therefore sum 2n . complexity o(n) . p.s. not called telescoping. telescoping in math when subsequent terms cancel each other.

say that, in method, pass in couple ienumerables (probably because i'm going bunch of objects db or something). then each object in objects1, want pull out diffobject objects2 has same object.id. i don't want multiple enumerations (according resharper) make objects2 dictionary keyed object.id. enumerate once each. (secondary question)is pattern? (primary question) what's big? @ point horrible pattern? how many objects many objects dictionary? internally, prevented ever having more 2 billion items. since way things positioned within dictionary complicated, if looking @ dealing billion items (if 16-bit value, example, 2gb), i'd looking store them in database , retrieve them using data-access code. i have ask though, objects1 , objects2 coming from? sounds though @ db level , much, more efficient doing in c#! you might want consider using keyvaluepair[]

string site_inclusion = "0;100"; (string inc: site_inclusion.split(";")) { if(!inc.equals(string.valueof(record.getattrs().get(new pdsxattrkey("siteid")).getvalue()))) { continue; } } and record.getattrs().get(new pdsxattrkey("siteid")).getvalue() returns 77 so code should going continue block right? not going continue? any suggestions? i suggest simplify code test what's going on. might have made mistake trying build example. string site_inclusion = "0;100"; (string inc: site_inclusion.split(";")) { string temp = string.valueof(record.getattrs().get(new pdsxattrkey("siteid")).getvalue()); if(!inc.equals(temp)) { system.out.println(inc + " != " + temp); continue; } system.out.println(inc + " == " + temp); }

perhaps me out this. using concept of cycle generate fibonacci series until reaching 10000 or little more that. so have code , it's supossed work , show me want doesn't. can tell me what's wrong it? opens doesn't work @_@ #include <stdio.h> #include <stdlib.h> int main() { int i=0,j=0,sum=1,num; while(sum>=1000){ { printf("%d\n",sum); i=j; j=sum; sum=i+j; } system("pause"); } the code made calculating fibonacci sequence following: #include <stdio.h> #include <stdlib.h> int main() { int i=0,j=0,sum=1,num; printf("introduce limit fibonacci sequence: "); scanf("%d",&num); while(sum<num) { printf("%d\n",sum); i=j; j=sum; sum=i+j; } system("pause"); } in first snippet, have typo while(sum>=1000){ should be whil...

how can display integer in label? doing calculating total , trying display in label. public partial class total : system.web.ui.page { int total; protected void page_load(object sender, eventargs e) { label1.text = server.htmlencode(request.cookies["confirm"]["quantity"]); int quantity = (int)session["textbox1value"]; if (request.cookies["user"]["items"] == "tyres") { total = 20 * quantity; label2.text = ??? } } } or there other way display total on same page? use label2.text = total.tostring(); or label2.text = convert.tostring(total); since text takes string have convert total integer value string calling tostring() or convert.tostring(int) .

insert method appends item end of linked list. can't figure out how code case node null, , want add it. struct node{ int data; node *next; node(int data):data(data),next(null){} void insert(int data){ if (this==null){ this=new node(data); // compiler complaining here. // how go setting value of (which presently null) new node? } } } you can not assign value this pointer special keyword , should point valid block of memory. looking @ usage, trying mean this: void insert(int data){ if (!next){ next = new node(data); }
