First step is create navigation interface which we will use on view model: public interface IViewNavigationService { void Initialize(INavigation navigation, SuperMapper navigationMapper); Task NavigateToAsync(object navigationSource, object parameter = null); Task GoBackAsync(); } ...

The showcase of Primefaces components you can find here and documentation is here Frontend needs to be saved as a XHTML file.

A path through every vertex exactly once is the same as ordering the vertex in some way. Thus, to calculate the minimum cost of travelling through every vertex exactly once, we can brute force every single one of the N! permutations of the numbers from 1 to N. Psuedocode minimum = INF for all per...

Notice that if we consider the path (in order): (1,2,3,4,6,0,5,7) and the path (1,2,3,5,0,6,7,4) The cost of going from vertex 1 to vertex 2 to vertex 3 remains the same, so why must it be recalculated? This result can be saved for later use. Let dp[bitmask][vertex] represent the minimum c...

from the root of your project ./node_modules/.bin/ngc -p src where src is where all your angular 2 code lives. This will generate a folder called ngfactory where all your compiled code will live. "node_modules/.bin/ngc" -p src for windows

// this is the static platform browser, the usual counterpart is @angular/platform-browser-dynamic. import { platformBrowser } from '@angular/platform-browser'; // this is generated by the angular compiler import { AppModuleNgFactory } from './ngfactory/app/app.module.ngfactory'; // note the...

Once you've installed react and react-router, Its time to use both of them together. The syntax is very simple, you specify the url and the component you want to render when that url is opened <Route path="hello" component={ HelloComponent } /> This means when the url path is hell...
