i'm studing computer engineering , have hard task. we have develop c# application can calculate factorial of big numbers without bigint . mean big numbers, 123564891...82598413! . , don't have use permission use custom libraries (like bigint ) . researched , found few questions this, this question different others because have calculate really big numbers without custom libraries . found poormans algorithm . it's calculating 10000 . it's not enough us. with teammates, found solution . let's factorial of 123 . 123 string . , , sum 123 , 122 times (it's equal 123 x 122) . , sum result 121 times. goes until reach 1. so, sum 2 strings. we create algorithm summing strings. getting last char of first number (3 of 123) integer (we can use integer, not bigint) . , last char of second number integer (2 of 122). sum them , found result number's last char (result = x...x5) . last char first char. result number . know, should use while() or for() loop, ,

i haven't been able understand why tooltip date off single day. believe x-axis correct, , i've been playing around it, killing me. how can fix this? i'm passing in json url endpoint variable jsondataurl. here example datapoint: [{date: "2013-01-01", value: 50}] and cssselector placeholder. here's code: $.getjson(jsondataurl, function(res) { var data = []; $.each(res, function(i, entry){ data.push( [new date(entry["date"]), entry["value"]] ); }); var opts = { yaxis: { min: 0}, xaxis: { mode: "time", timeformat: "%m-%d"}, series: { lines: { show: true }, points: { show: true } }, grid: {hoverable: true, clickable: true} }; $.plot($(cssselector), [data], opts); $(cssselector).bind("plotclick", function(event, pos, item) { if (item) { var x = parseint(item.datapoint[0]), y =

i couldn't find similar question decided ask (this may more appropriately asked on programmers, if apologize in advance). is bad practice use dot notation along message call, so: [self.view addsubview:otherview]; as opposed to: [[self view] addsubview:otherview]; i curious, looked tad bit strange don't see wrong it. i'm still relatively new objective-c , not familiar best practices of note yet. there's nothing wrong it. it's merely stylistic question. use whichever 1 prefer. (the dot notation, way, has advantage compiler throws error if you're calling undeclared property getter or setter dot notation, can potentially rid of strange run-time errors @ compile time.)

solution because objective-c doesn't encode & (because reserved) should create own method. source: sending amp (&) using post obj-c for ios , android app use php script data. script has 1 argument link. script looks this: $link= urlvariable('link'); $source = file_get_contents($link); $xml = new simplexmlelement($source); //do stuff xml but when send link & symbol crashes on file_get_contents warning: file_get_contents(https://www.example.com/xxxx/name_more_names_) [function.file-get-contents]: failed open stream: http request failed! but full argument is name_more_names_&_more_names_after_the_ampersand.file i tried encoding link before sending file_get_contents no luck. also tried: function file_get_contents_utf8($fn) { $content = file_get_contents($fn); return mb_convert_encoding($content, 'utf-8', mb_detect_encoding($content, 'utf-8, iso-8859-1', true)); } with same results. does know why

i using script auto refresh content every 10 seconds. var auto_refresh = setinterval( function () { $('#stats').load('stats.php').fadein("slow"); }, 10000); however, need add start/pause button start , pause refresh. how can ? in general sense can pause effect setinterval() adding flag: var paused = false, auto_refresh = setinterval(function (){ if (paused) return false; $('#stats').load('stats.php').fadein("slow"); }, 10000); $("#idofpausebutton").click(function() { paused = !paused; this.value = paused ? "restart" : "pause"; }); i find method simpler using clearinterval() pause , setinterval() again restart. obviously assumes use single button pause/restart: <input id="idofpausebutton" value="pause" type="button"> demo: http://jsfiddle.net/nnnnnn/nwa56/
