问题 I have an array of posts that I am trying to sort by date - I cant figure out how to get access to the date though, since the array is a list of react components, not objects. Here is how the code is working now... The user searches for 'bands' and it creates an array of all the band objects. Each band object has a bunch of posts in band.posts. So to get all the posts out of all of the bands I map through all the bands, then for each band I map through all of their posts. Each post then goes

问题 I have issues while using sortItems() on a QListWidget. Here is what happens: Changes this: A z d C E o I to this: A C I d e o z But i want it to be: A C d e I o z Any way to change to make it sort like that? 回答1: QListWidget uses the DisplayRole (the item's text) for sorting and calls QString::localeAwareCompare on them. To override the default, you can either change the locale used (see QLocale) or have your own QListWidgetItem subclass reimplementing QListWidgetItem::operator< and let it

问题 Given a list of strings, I want to return a list with the strings in sorted order, except group all the strings that begin with 'x' first. For example: ['mix', 'xyz', 'apple', 'xanadu', 'aardvark'] Should yield: ['xanadu', 'xyz', 'aardvark', 'apple', 'mix'] I know it can be done by making 2 lists and sorting each of them before combining them, but I'm not sure how to write the condition in which 'x' is the first character. 回答1: sorted or list.sort accepts optional key keyword argument. That

问题 I have the following domain objects: @Entity public class Item { @Id @GeneratedValue(strategy = GenerationType.AUTO) private Long id; private String name; @OneToMany private List<PropertyDefinition> propertyDefinitions; } @Entity public class PropertyDefinition { @Id private Long id; private final String name; private final String value; } I would like to sort the items for example "title" named PropertyDefinition.value How could I do that with Spring Data JPA? Iterable<Item> items =

问题 This is my folder structure. /home/files/encounters 9-22-11-0.jpg .. /home/files/encounters 9-22-11-[n].jpg puts Dir.glob("/home/files/*.jpg")[0] When i execute the above code, it displayed the sixth file (index 5 => /home/files/encounters 9-22-11-5.jpg), but actually i need the output as first file(index 0 => /home/files/encounters 9-22-11-0.jpg) How can i sort the files as user defined sorting order?. like When i tried.. ..[0] => /home/files/encounters 9-22-11-5.jpg ..[1] => /home/files

问题 use List::MoreUtils 'uniq'; print join ", ", sort uniq ("b", "a", "a"); results in Argument "a" isn't numeric in sort at ... print join ", ", uniq sort ("b", "a", "a"); works as expected. print join ", ", sort {$a cmp $b} uniq ("b", "a", "a"); works too - but what is the problem with the first example? 回答1: That code falls under the sort invocation of sort SUBNAME LIST ... If SUBNAME is specified, it gives the name of a subroutine that returns an integer less than, equal to, or greater than 0
