i need create book index method can pair multiple values 1 key e.g key - "beck,kent" value - 27 23 76 is possible? the import ou.*; open university library , should not affect anything. import java.util.*; import ou.*; public class bookindex { public map<string, integer> index() { map<string, integer> actual = new hashmap<>(); return actual; } thanks how using integer array instead of integer in map<string, integer> . hashmap<string, integer[]> anewmap = new hashmap<string, integer[]>(); anewmap.put("beck,kent",new integer[] { 27, 23, 76});

i know answer using median of medians can explain how it? there linear time algorithms this, page might helpful, http://en.wikipedia.org/wiki/selection_algorithm , if still confused ask basically way selection algorithm works quicksort sorts on side of pivot each time. goal keep partitioning until choose pivot equal index of element trying find. here java code found quickselect: public static int selectkth(int[] arr, int k) { if (arr == null || arr.length <= k) throw new error(); int = 0, = arr.length - 1; // if == reached kth element while (from < to) { int r = from, w = to; int mid = arr[(r + w) / 2]; // stop if reader , writer meets while (r < w) { if (arr[r] >= mid) { // put large values @ end int tmp = arr[w]; arr[w] = arr[r]; arr[r] = tmp; w--; } else { // value smaller pivot, skip r++; } } // if stepped (r++) need step 1 down if (arr[r] > mid) r--; // r pointer on end of first k elemen...

the ember.js apps app = ember.application.create(); and app = ember.application.create(); app.applicationcontroller = ember.controller.extend(); do same because ember automagically generates applicationcontroller. correct? so why can access app.applicationcontroller in javascript console second app not first one? when automagically generated should able access in console. wrong assumption? it's created in both cases, try in javascript console: //use debug purposes app.__container__.lookup('controller:application'); this should give applicationcontroller instance in both cases altough define controller so: app.applicationcontroller = ember.controller.extend(); if want hook controller hope helps
