i want function running after rendering in emberjs has happened (globally), after "switch" in {{#if}}-{{else}}-block. subscribing render event with ember.subscribe("render", { before: function (name, timestamp, payload) { }, after: function (name, timestamp, payload) { // function call } }); works quite not called after rerendering via if-else-switch. so want listen rendering globally , noticed @ end of it. best regards martin

given matrix of size m * n, place k students in such way cheating in exam minimized what thought : with brute force approach , create possible combination of students placements , return 1 minimum cheating score, while cheating score defined sum of manhattan distances between each 2 students. the time & space complexity of approach bad, better solution ? 1) geometric intuition -- perhaps try placing first 4 @ outer corners of square, spiral inwards there? this approx work "pythagorean distance", maybe can adapt "manhattan distance" equivalent of inward spiralling path & place students linearly along that. 2) or, place students sequentially @ next cheating-minima; then, once students placed, perturb locations achieve "overall minima". i 2) best approach.
