reverse

问题 I am trying to reverse an array in 2 ways: 1) By creating a new array which was very easy: public static int[] reverse(int[] array) { int[] reverseArray = new int[array.length]; for(int i = 0; i < reverseArray.length; i++) { reverseArray[i] = array[array.length - i - 1]; } return reverseArray; } 2) The second method I got my answer but I actually don't understand it very well, it actually makes use of swapping, giving the value of the array to a temporary variable then changes it and returns

问题 Following REST it is advisable that API is discoverable and should be interlinked. Does ServiceStack support any kind of reverse routing? I'm looking for something like Url.RouteLink in ASP MVC. 回答1: There's some mixed concepts stated here. In and effort of trying to comply with REST you wish to embed URI's in your responses. How best to achieve embedding URI's in your responses. You've assumed a "Reverse Routing" mechanism is how this should be done. REST style vs Strong-typing I want to be

问题 I have finished a homework assignment for my programming class. I was supposed to create a Prolog program that reverses a list. I, however, am having trouble understanding why exactly it works. %1. reverse a list %[a,b,c]->[c,b,a] %reverse(list, rev_List). reverse([],[]). %reverse of empty is empty - base case reverse([H|T], RevList):- reverse(T, RevT), conc(RevT, [H], RevList). %concatenation What exactly is RevT in this case? I know it is supposed to represent the reverse of T or the rest

问题 When I reverse iterate over an ArrayList I am getting a IndexOutOfBoundsException. I tried doing forward iteration and there is no problem. I expect and know that there are five elements in the list. The code is below: Collection rtns = absRtnMap.values(); List list = new ArrayList(rtns); Collections.sort(list); for(int j=list.size();j>0;j=j-1){ System.out.println(list.get(j)); } Forward iteration - which is working fine, but not useful for me: for(int j=0;j<list.size();j++){ System.out

问题 If we have a neural network such as the multilayer perceptron back propagation neural network that uses sigmodial logistic activation functions is it possible to feed the network outputs and have it compute back a set of inputs? Since we can reverse the activation function by using the natural logarithm and inverse operations until we have a sum value that is made up of all the weights multiplied by their inputs i would think that it would be possible to at least get sets of possible inputs

问题 This question already has an answer here : Transpose matrix: swapping elements doesn't alter values (1 answer) Closed 11 months ago . I am trying to reverse an array of 15 numbers by using a for loop, but for some reason the array order stays the same. My code looks like this: int main() { int arr[15] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 }; int i, j, temp; for (i = 0; i < 15; i++) { temp = arr[15 - i - 1]; arr[15 - i - 1] = arr[i]; arr[i] = temp; } j = 0; do { std::cout <<

问题 I wrote this function to reverse a string in C, but when switching characters in the string the program crashes. I have no idea what's causing it, so any help would be appreciated. void reverse(char s[]) { char c; int i; int j; for (i = 0, j = (strlen(s) - 1); i < j; i++, j--) { c = s[i]; s[i] = s[j]; //An error occurs here s[j] = c; } printf("%s", s); } main() { reverse("Example"); } 回答1: read this for more information What is the difference between char s[] and char *s?

问题 Can anyone help in this php page navigation script switch on counting normal serial number? In this script there is a var called "page_id" - I want this var to store the real page link by order like 0, 1, 2, 3, 4, 5 ... <? $onpage = 10; // on page /* $pagerecord - display records per page $activepage - current page $records - total records $rad - display links near current page (2 left + 2 right + current page = total 5) */ function navigation($pagerecord, $activepage){ $records = 55; $rad =

问题 I had a job interview today. During it I was asked to write down an algorithm that will reverse a list. First I offered the answer using the reversed() method: x = [1,2,3,4,5] y = reversed(x) for i in y: print i The senior developer conducting the interview asked me if I know another way, upon which I wrote down the other known method with slicing: x = [1,2,3,4,5] y = x[::-1] Unfortunately he was unhappy with this solution as well and asked me to think of another one. After few minutes I said
