This has logarithmic time complexity. After this I tried to generalize it to finding kth smallest among two sorted arrays. Here

Each entry has a target value (by order of importance): Likely Supporter, GOTV, Persuasion, Persuasion+GOTV Unfortunately if I do df_targets = df_targets.sort("target") the ordering will be alphabetical ( GOTV , Likely Supporter , ...). I was hoping for a keyword like list_ordering as in: my_list = ["Likely Supporter", "GOTV", "Persuasion", "Persuasion+GOTV"] df_targets = df_targets.sort("target",

(they are numerical IDS) ArrayList<String> tempList = new ArrayList<String>(); for(String s : AddressBook){ tempList.add(s); Collections.sort(tempList ); } System.out.println(tempList); 回答1: Yes this is fairly trivial in Java 8: Collections.sort(list, Comparator.comparing(s -> s.subString(4)); 回答2: You can do it by supplying your own Comparator implementation. Collections

EDIT: git effort is just a bash script you can find here and adapt to your needs if you need something more special. 回答2: You could do something like the following: git log --pretty=format: --name-only | sort | uniq -c | sort -rg | head -10 The log just outputs the names of the files that have been changed in each commit, while the rest

But it seems the order of the data was not ordering the same way when i used a sort function. Assume that the list contains 4 ComputeItem and all their A are set to 1, the B, C, D of all are set to zero. CASE 1: ItemList = ItemList .OrderByDescending(m => m.A) .ThenBy(m => m.B) .ThenBy(m => m.C) .ThenBy(m => m.D) .ToList<ComputeItem>(); versus CASE 2: ItemList.Sort( delegate(ComputeItem item1, ComputeItem item2) { if (item1.A == item2.A) { if (item1.B == item2

T1 -------- Id, Timestamp, Text1 T2 -------- Id, Timestamp, Text2 With SQL it can be done this way: SELECT TOP 10 * FROM ( SELECT [Timestamp], [Text1] FROM T1 UNION SELECT [Timestamp], [Text2] FROM T2 ) as x ORDER BY [Timestamp] Q: How can I do that task using EF linq? 回答1: You need an anonymous type with the same property names and types before you can do an Union operation: var t1List = from a in allT1 select new { TimeStamp = a.TimeStamp, Text = a.Text1 }

Here i need to sort the bars based on the values(I mean in ascending/descend manner). Is there any inbuilt function available for sorting in nvd3. Or how can I achieve the sorting thing. nv.addGraph(function() { var chart; chart = nv.models.multiBarChart() .margin({bottom: 100}) .transitionDuration(300); chart.options( {delay: 1200}); chart.multibar .hideable(false); chart.xAxis //.axisLabel("Modules") .rotateLabels(45); chart.yAxis .tickFormat(function(d) { return d + "%";
