c# - Why when I sort a list full of 0's it gets mixed up? -


i'm trying rate gin's popularity, read in gin list text file , each gin starts popularity of 0, when sort list comes out mixed, not in it's original alphabetical order if not sorted.

no sorted -

here code i'm using -

using unityengine; using system.collections; using system.collections.generic;  public class ginlistclass : monobehaviour {     [header("the text file holding gin's, country, abv , price")]     public textasset gintextfile;     [header("the lists, public debugging")]     public list< string > ginstring = new list< string >();      private int rating;     private int linesinfilecount;  void start ()  {     rating = 0;     list<ginlist> gins = new list<ginlist>();      string[] linesinfile = gintextfile.text.split('\n');      foreach (string line in linesinfile)     {         linesinfilecount++;          ginstring.add(line);     }     (var = 0; < linesinfilecount; i++)     {         gins.add( new ginlist(ginstring[i], ginstring[i+1], ginstring[i+2], ginstring[i+3], rating+random.range(0,100)));         i+=4;     }     gins.sort();     //gins.reverse();      debug.log("a .. gin count " + gins.count);      foreach(ginlist gin in gins)     {         debug.log(gin._ginname + " - " + gin._country + " - " + gin._abv + " - " + gin._price + " - " + gin._pop);     }     gins.clear(); }

}

and -

using unityengine; using system.collections; using system.collections.generic;  public class ginlistclass : monobehaviour { [header("the text file holding gin's, country, abv , price")] public textasset gintextfile;  [header("the lists, public debugging")] public list< string > ginstring = new list< string >();  private int linesinfilecount;  void start ()  {     list<ginlist> gins = new list<ginlist>();      string[] linesinfile = gintextfile.text.split('\n');      foreach (string line in linesinfile)     {         linesinfilecount++;          ginstring.add(line);     }     (var = 0; < linesinfilecount; i++)     {         gins.add( new ginlist(ginstring[i], ginstring[i+1], ginstring[i+2], ginstring[i+3], random.range(0,100)));         i+=4;     }     //gins.sort();     //gins.reverse();      debug.log("a .. gin count " + gins.count);      foreach(ginlist gin in gins)     {         debug.log(gin._ginname + " - " + gin._country + " - " + gin._abv + " - " + gin._price + " - " + gin._pop);     }     gins.clear(); }

}

if give gin's rating sort correctly.

can pleas point me in right direction, thank you.

some sort algorithms stable, not. probably, sort algorithm used library not stable, i.e., may reorder items compare equally.

as solution, order first popularity, if have same popularity, sort name. don't know c# (or whatever using) should pseudo-code

int compare(const myobject & i1, const myobject & i2) {     if(compare(i1.popularity, i2.popularity) == 0) {         // reverse sort popularity         return -compare(i1.popularity, i2.popularity);     }        return compare(i1.name, i2.set2id); }

use as

gins.sort(compare);

edit: solution

Is there a better way to structure post methods in Class Based Views -

i'm using class based views in django , never specify url in ajax calls , omit action parameter in form because know these requests go through post method of class based view. notice view - profile page make many requests depending on user updating on page - post method become convoluted , if/else mess example: def post(self, request, *args, **kwargs): # handle user changing available date if request.post.get('availabledate') != none: self.updateavailabledate(request) return jsonresponse({'result':'success'}) if request.post.get('newprojectname') != none: creative_user = creativeuserprofile.objects.get(id = request.user.id) project = project.create_project(creative_user, request.post['newprojectname']) project.save() return jsonresponse({'projectid': project.id }) if request.post.get('projectimage') != none , request.files['file']: proj

performance - Why is XCHG reg, reg a 3 micro-op instruction on modern Intel architectures? -

i'm doing micro-optimization on performance critical part of code , came across sequence of instructions (in at&t syntax): add %rax, %rbx mov %rdx, %rax mov %rbx, %rdx i thought had use case xchg allow me shave instruction , write: add %rbx, %rax xchg %rax, %rdx however, dimay found agner fog's instruction tables , xchg 3 micro-op instruction 2 cycle latency on sandy bridge, ivy bridge, broadwell, haswell , skylake. 3 whole micro-ops , 2 cycles of latency! 3 micro-ops throws off 4-1-1-1 cadence , 2 cycle latency makes worse original in best case since last 2 instructions in original might execute in parallel. now... cpu might breaking instruction micro-ops equivalent to: mov %rax, %tmp mov %rdx, %rax mov %tmp, %rdx where tmp anonymous internal register , suppose last 2 micro-ops run in parallel latency 2 cycles. given register renaming occurs on these micro-architectures, though, doesn't make sense me done way. why wouldn't register renamer

jquery - Responsive Navbar with Sub Navbar -

good day, forgive me nav vocabulary not best. if question confusing apologize. i'm working on navigation bar needs centered on page @ 768px , above. items in nav open (or perhaps toggle) subnav lives directly below. these nav should appear centered on page. i have been able work through responsive portion of nav bar, having main items align vertically , sub nav menu of each item roll out below, , gave them indent separation. working well. however, issue not responsive side, behavior @ width greater 768px. happens toggling menu's sub navigation pushes other main items down page below sub nav. here's code: $(document).ready(function () { //stick in fixed 100% height behind navbar don't wrap $('#slide-nav.navbar-inverse').after($('<div class="inverse" id="navbar-height-col"></div>')); $('#slide-nav.navbar-default').after($('<div id="navbar-height-col"></d
