The ListView is populated by a SQL Query which correctly sorts Strings and Integers together ( code shown below ). For Example: String & Integer Sorting Problem The following JobNumber strings are considered as sorted "10", "1", "2", "3" Using my SQL Query, they will become "1", "2", "3", "10" SQL String & Integer Sorter Here is the Query I use to sort Strings and

问题 This question is a follow up from another I had here SAS: Data step view -> error: by variable not sorted properly; I am opening a new question as the desired solution is slightly different: As I am looping through several input files, one of the raw-files is not properly sorted, I wonder what I could do to make my program to skip that particular input file and just continue? Quote: I am using a macro to loop through files based on names and extract data which works fine for the majority of

问题 It is necessary to make sorting of structures on a field (char last_name [256];) structures Pers and display the user in the console. How to do it? Thank you in advance.

问题 I was trying to sort an array of divs so that if a is below or to the left of b , a is before b . After a couple hours in CodePen, I realized that if an array is ten or more items in length, Chrome will sort the items out of order, at least with this compare function: var array = [0,1,2,3,4,5,6,7,8,9,10]; array.sort(function(a, b) { return -1; }); Chrome returns: [0, 2, 3, 4, 1, 6, 7, 8, 9, 10, 5] See on CodePen If you log a and b inside the sort function, it becomes obvious why it happens-

问题 The line self.tableView.setSortingEnabled(True) sorts a table view when clicking on the header, but it sorts incorrectly. That is, it thinks every column is a string (e.g. it sorts numbers like 1,11,12,2,22,3 , etc). How do I correct this? My code: self.model = QtGui.QStandardItemModel() with open(file_name_temp, "rt") as fileInput: i = 1 for row in csv.reader(fileInput): item = QtGui.QStandardItem() for field in row: items = [ item.setData(field, QtCore.Qt.UserRole) ] print(items) self.model

问题 Hi I have a question about Batcher's odd-even-merge sort. I have the following code: public class Batcher { public static void batchsort(int a[], int l, int r) { int n = r-l+1; for (int p=1; p<n; p+=p) for (int k=p; k>0; k/=2) for (int j=k%p; j+k<n; j+=(k+k)) for (int i=0; i<n-j-k; i++) if ((j+i)/(p+p) == (j+i+k)/(p+p)) exch(a, l+j+i, l+j+i+k); } public static void main(String[] args) { int a[] = new int[] {2, 4, 3, 4, 6, 5, 3}; batchsort(a, 0, a.length - 1); for (int i=0; i<a.length; i++) {
