问题 I sent a friend a workbook with a macro that includes some sorting. When he tries it he gets: Run-time error '438' Object doesn't support this property or method. He clicks Debug to see the offending code and is taken to a line or two of (fairly simple) data sorting. The text that gets highlighted is: ActiveWorkbook.Worksheets("Data Set").Sort.SortFields.Add2 Key:=Range( _ "H2:H8065"), SortOn:=x1SortOnValues, Order:=x1Descending, DataOption:= _ x1SortNormal Those 3 lines are it, part of a

问题 So I have this code which I found on the internet which takes an array of negative and positive numbers and rearranges the array so all negative numbers are before the positive ones. But the position of appearance of each number has to remain the same. So for example if i have -2 5 -9 ..... , in the organized array -2 still has to be the first number of the negative ones and -9 has to be the second of the negative ones, also 5 has to be the first number of the positive ones. Example: Input:

问题 I would like to count how many times is every string in array and sort them by number of times they exist in array I have this code now hlasy.sort(); var zaciatok = null; var pocet = 0; for (var i = 0; i < hlasy.length; i++) { if (hlasy[i] != zaciatok) { if (pocet > 0) { console.log(zaciatok + ' má ' + pocet + ' hlasov'); } zaciatok = hlasy[i]; pocet = 1; } else { pocet++; } } if (pocet > 0) { console.log(zaciatok + ' má ' + pocet + ' Hlasov'); } it works, but it outputs strings from array

问题 I am needing to sort a list that contains tuples inside. I can sort them using key=lambda . The list is larger than 1000 elements. >>> a = [(<object>, 4), (<object>, 5), (<object>, -2)....] >>> b = sorted(a, key=lambda tup: tup[1]) Is there a faster way to accomplish this? 回答1: You can use itemgetter >>> from operator import itemgetter >>> a = [(None, 4), (None, 5), (None, -2)] >>> b = sorted(a, key=itemgetter(1)) >>> b [(None, -2), (None, 4), (None, 5)] Now if you want to look at the

问题 Beginner in Java using an old textbook and Head First: Java books to figure some stuff out. I have three arrays all parallel. I need to be able to sort by Title, Author, or Page Count based on user selection. I can sort one using Arrays.sort() but I'm getting hung up on how to sort the other two arrays to correspond to the new sorted one. Say I sort the BookTitle array, but I'm going to need to display the proper author and page count of its respective arrays and I'm stumped. do { entry =
