javascript - How to find subgraph -


i trying show specific subgraph of disconnected directed graph containing selected node user. parents, parents of parents... , children, children of children until roots , leaves. need hide rest of graph.

any appreciated.

as @aksam suggested, like:

var selectednode = cy.$('node:selected'); var visitedarr = [ selectednode ];  cy.elements().bfs({ // or dfs   roots: selectednode,   visit: function(i, depth, v, e, u){     visitedarr.push( v );   },   directed: false // or preference });  var subgraph = cy.collection( visitedarr );  cy.batch(function(){   cy.elements().not( subgraph ).addclass('hidden');   subgraph.removeclass('hidden'); });

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
