Can't sort array of structures alphabetically

First of all, the algorithm you are trying to build is not sorting. What you have here is (after fixing issues described below) one iteration of bubble sort. To make it actually sort the array you need to call dictioarySort 10 times. See https://en.wikipedia.org/wiki/Bubble_sort for more details. Now to the...
Reading and listing objects in the order they appear in the source file in R

MongoDB custom sorting with the other values?
The most efficient approach would be to update the rank field when you change the values in your application code (i.e. don't allow time and velocity to be set without also recalculating the rank). You can then add an appropriate index (or indexes) including the rank field to support your...

This solution is pretty slow, but should work dbArray.sort(function(a,b) { return stdArray.indexOf(a) - stdArray.indexOf(b); }); If you're concerned about performance, you could use a map to track the index of each item to avoid scanning the array for each comparison. var indexMap ={}; stdArray.forEach(function(str) { indexMap[str]=stdArray.indexOf(str); }); dbArray.sort(function(a,b) { return...

As @JaredHoberock pointed out, probably the key issue is that you are trying to compile a .cpp file. You need to rename that file to .cu and also make sure it is being compiled by nvcc. After you fix that, you will probably run into another issue. This is not...
Determine sorting algorithm from results
We can tell that this isn't a quadratic-time algorithm like selection sort or insertion sort, since raising the input size by a factor of 10 raised the runtime by a factor of 13-19. This is behavior we'd expect from an O(n*log(n)) average-case algorithm, like mergesort or a good quicksort. We...
EXC_BAD_ACCESS error occurring when running recursive merge sort method in a thread
c++,multithreading,sorting,recursion
You problem originates in this line: int newArray[maxCount + 1]; You are trying to allocate ~250000 ints on the stack (on most 32 bit platforms it will take ~1MB of memory). Your thread's stack may not be able to do this. By the way, you should not do this -...
How to swap two dates in swift
This function is named sort, but it doesn't actually sort the array. If you're actually trying to sort the array, you should just use the builtin sort function: missions.sort { $0.createdAt.timeIntervalSince1970 > $1.createdAt.timeIntervalSince1970 } The function as you've written it, were it compilable, would always cause a fatalError because you...
Ranking with time weighting
To clarify @Dan Getz and add @collapsar answer I will add the following: Dan's Formula is correct: (score1 * weight1 + ... + scoreN * weightN) / (weight1 + ... + weightN) The beauty of the weighted average is you get to choose the weights! So we choose days since...
Sorted List for Doubly Linked List
python,list,sorting,doubly-linked-list
If you want a list to remain sorted, ensure that you insert elements into it in sorted position. Finding this position should be straightforward. The doubly linked list class, has only a Double Ended Queue (dequeue) interface, so insertion isn't actually possible with the current methods and you will need...
Sort function giving floating point exception for a large input of 0's
c++,sorting,radix-sort,floating-point-exceptions
Your radixSort function violates the Compare requirements, namely irreflexivity (that is, radixOrder(x, x) must return false but it returns true because the execution goes to the first if branch). So you get a classic example of undefined behavior here. I believe that piece of code should be rewritten somehow like...
Read words/phrases from a file, make distinct, and write out to another file, in Java
java,file,sorting,distinct-values
You can leverage: NIO (Non-blocking I/O) API (available since Java 7) Streams API (available since Java 8) …to solve the problem elegantly: public static void main(String... args) { Path input = Paths.get("/Users/yourUser/yourInputFile.txt"); Path output = Paths.get("/Users/yourUser/yourOutputFile.txt"); try { List<String> words = getDistinctSortedWords(input); Files.write(output, words, UTF_8); } catch (IOException e) {...
