let's have 500x500 2d grid (from -250 250). each cell of grid has value, 0 100. what i've been trying keep list of cell value lower 50 starting @ point (0, 0), not keep points, outer points (perimeter, bounds, cell value lower 50 not have 4 adjacent cells value lower 50). the way implemented algorithm, keep list of points. how should modify it? optimize code if possible (i can have bigger grids), prefer not iterate again. pointlist pointswithvaluebelow50; // list of points value below 50 map<point, bool> pointdiscovered; // map of points passed through point = {0,0}; point b; int value; queue q; q.enqueue(a); pointdiscovered[a] = true; while(!q.isempty()) { = q.dequeue(a) value = calculatevalue(a); // random method verify if points has value below 50 in grid if (value < 50) { pointswithvaluebelow50.add(a); b[0] = a[0]+1; b[1] = a[1]; if(pointdiscovered[b] == false) { q.enqueue(b) ...

i have seen various frameworks targeted in project.json files, using names such netcore50 , dotnet , dnx451 , net45 , , others. documentation "framework" section project.json not (yet) specify how use section different frameworks. what frameworks available , name should used in project.json target each? update 3 full list see target frameworks . the common tfms asp.net app developers need know are: netcoreappx.y = application targets .net core x.y (e.g. netcoreapp1.0 = .net core 1.0) netstandardx.y = library targets .net standard x.y . (e.g. netstandard2.0 = .net standard 2.0). .net standard libraries can work on desktop .net, windows phone, mono, , others. net4xy = library or console app targets desktop .net framework 4.x.y (e.g. net452 or net46 ) update 2 (dec 9, 2015) somewhat official docs available dotnet. see .net platform standard → nuget for libraries targeting multiple platforms adhere .net standard , these tfms (target fram...
