Thanks. 回答1: Since version 4.1, Spring Framework provides a way to generate routes to resources from templates (i.e. reverse routing in views). You can check the reference documentation on the subject,

问题 Language: C I am trying to program a C function which uses the header char *strrev2(const char *string) as part of interview preparation, the closest (working) solution is below, however I would like an implementation which does not include malloc... Is this possible? As it returns a character meaning if I use malloc, a free would have to be used within another function. char *strrev2(const char *string){ int l=strlen(string); char *r=malloc(l+1); for(int j=0;j<l;j++){ r[j] = string[l-j-1]; }

问题 How to reverse regular expression in Java? For example, 'ab.+de' => 'ed.+ba'. 回答1: wow. You need to build a parser for regular expression and reverse all of the tokens/parts. in this case ab.+de is a , b, .+ , d , e and reverse this is e, d, .+, b, a now imagine groups ((ab)(.+de)) the reverse is ((ed.+)(ba)) 回答2: It would actually be much easier to reverse the haystack than the needle. And since Matcher takes a CharSequence instead of a String , you can do so with trivial overhead by simply

问题 In discussion of this answer we realized that tuples do not have a __reversed__ method. My guess was that creating the iterator would require mutating the tuple. And yet tuples play fine with reversed . Why can't the approach used for reversed be made to work for __reversed__ as well? >>> foo = range(3) >>> foo [0, 1, 2] >>> list(foo.__reversed__()) [2, 1, 0] >>> foo [0, 1, 2] >>> bar = (0, 1, 2) >>> list(bar.__reversed__()) Traceback (most recent call last): File "<stdin>", line 1, in

问题 Using if and while / do - while , my job is to print following user's inputs (string value) in reverse order. For example: input string value : "You are American" output in reverse order : "American are You" Is there any way to do this? I have tried string a; cout << "enter a string: "; getline(cin, a); a = string ( a.rbegin(), a.rend() ); cout << a << endl; return 0; ...but this would reverse the order of the words and spelling while spelling is not what I'm going for. I also should be

问题 I want to write a function in lisp that reverses all elements from the list using map functions but I don't have any idea how to start this.. I think I have to use the built in reverse function somehow.. For example if I have the list (1 2 3 (4 5 6 (7 8 9))) I would get (((9 8 7) 6 5 4) 3 2 1) or if I had the list(1 2 3 (4 5) (6 7)) I would get ((7 6) (5 4) 3 2 1) .. Any help is appreciated! 回答1: Just a quick answer, not sure about efficiency/elegancy: (defun reverse-deeply (list) (mapcar #'

问题 I have a ObservableCollection which is binded as ItemSource to my ComboBox. It's a ComboBox which shows you your changes which you've done. My Problem is now, that the newest Change is displayed on the bottom of the list. I tried to reverse it in the property, but when I return ComboboxName.Reverse() I get an IEnumerable back. I also don't want to make a 2nd collection with the reversed data. An other way would be to solve this in XAML. Does someone have an idea how I can do that? I found

I am looking for a way , possibly
