big o - What Big-O notation would this fall under? -

what big-o notation fall under? know setsearch() , removeat() of order o(n) (assume either way). know without loop it'd o(n), certain, confused how calculate becomes loop thrown it. i'm not great @ math... so. o(n^2)?

public void removeall(dataelement clearelement) { if(length == 0) system.err.println("cannot delete empty list."); else { for(int = 0; < list.length; i++) { loc = seqsearch(clearelement); if(loc != -1) { removeat(loc); --i; } } } }

if removeat() , seqsearch() o(n) respect length of list yes, algorithm of order o(n^2). because within loop phone call seqsearch every time, possibility of calling removeat(loc). means each iteration doing either n or 2n operations. taking worst case, have 2n^2 operations o(n^2).

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...

javascript - mongodb won't find my schema method in nested container - i trying access method of schema stored within mixed container. here situation : have cases model can many different things, have schema each of these things stored in "casecontent" mixed property. var caseschema = mongoose.schema({ casecontent : {}, object : {type:string, default : "null"}, collision : {type : boolean, default : false} }); the casecontent property filled model of 1 of schemas, 1 exemple : var treeschema = new mongoose.schema({ applecount : {type : number, default : 3} }); treeschema.methods.dostuff = function (data) { console.log('hey, listen'); homecoming true; }; then, want utilize method of schema original container : caseschema.methods.dostuff = function (data) { if (this.casecontent.dostuff !== undefined) { this.casecontent.dostuff(); console.log('it worked'); } else { ...
