i given following question in technical interview: how remove duplicates unsorted array? one option thinking of: create hash map frequency of each number in array go through array , o(1) lookup in hash map. if frequency > 0, remove number array. is there more efficient way? another option sort array o(nlog n) using quick sort or merge sort then iterate through array , remove duplicates why option 1 better option 2? i cannot use functions work array_unique. instead of removing object array if hash map says there duplicate, why don't build new array each item in hash map, , add array if there isn't duplicate? idea save step of having 2 arrays equal overhead @ start. php sucks @ garbage collection if start massive array, though unset value, might still hanging around in memory.

the common way send request server is $.get('link/to/send', { param1: "value1", param2: "value2" }, function(result) { // ... etc }); now if want send dynamic parameter names, can jquery support that? (i.e. need write generic code can specify parameter names @ runtime) this not jquery dependent, it's vanilla javascript. you should this: var objtosend = {}; objtosend["param1"] = "value1"; objtosend["param2"] = "value2"; $.get('link/to/send', objtosend, function(result) { // ... etc });

hi html code drag used is: <div class="btn-event" dnd-type="'newevent'" dnd-draggable="event" dnd-effect-allowed="copy" dnd-copied=""> <div class="icon"> <i class='demo'></i> </div> <span class="label" title="object name"> {{o.name}} </span> </div> the code drop is: <div class="row slot-body" dnd-list="sequenceslot.events" dnd-allowed-types="['newevent']" dnd-drop="drop(event, index, item, external, type, dropped item)" dnd-dragover="drop.validate(event, index, type)"> are supposed search dragabble ? or css ? use draganddrop() action method, example: browser.actions().draganddrop( element(by.css("div[dnd-draggable]")), element(by.css("div[dnd-dragover]")) ).perform();
