问题 I have that previous question about this quicksort here.The prolog code for quicksort: gt(X,Y):- X @>Y. conc([],List, List). conc([Head|Tail], List1, [Head|List2]):- conc(Tail, List1, List2). quicksort([],[]). quicksort([X|Tail],Sorted):- split(X,Tail,Small,Big), quicksort(Small,SortedSmall), quicksort(Big,SortedBig), conc(SortedSmall,[X|SortedBig],Sorted). [1]split(X,[],[],[]). [2]split(X,[Y|Tail],[Y|Small],Big):- gt(X,Y),!, split(X,Tail,Small,Big). [3]split(X,[Y|Tail],Small,[Y|Big]):- split

What's the relationship between processor's call stack and Python's frame object?

阅读更多关于 What's the relationship between processor's call stack and Python's frame object?

问题 In my mind, the Python interpreter is simulate what a CPU run binary code. And, processor will have a call stack when you invoke a function, Python as well. So, is there a corresponding between the Python stack frame and processor's call stack? Like when we invoke a function in Python interpreter, it made a new stack frame, and what happened to processor is it push esp , mov ebp, esp , and so on. 来源： https://stackoverflow.com/questions/55843979/whats-the-relationship-between-processors-call

Reduce stacktrace of executing frame

阅读更多关于 Reduce stacktrace of executing frame

问题 I'm doing my best to not be vague here and this all could be solved with a while loop, but as an exercise I've gone against the best practice of using a while loop in hopes to learn something new. I'm re-learning some basics of CPU architecture, and thought it'd be a fun project to implement CPU emulation with "actual" JMP logic, or as close to it as possible in software. However, I'm getting stuck on a rendering process of said logic. The code is (according to my best judgement) irrelevant

I hope you can help me Thanks 回答1: You can do StringWriter stackTraceWriter = new StringWriter(); throwableElement.printStackTrace(new PrintWriter(stackTraceWriter)); textArea.setText(throwableElement.toString() + "\n" + stackTraceWriter.toString()); 来源： https://stackoverflow.com/questions/33411873

Free/delete strtok_r pointer before processing complete string?

阅读更多关于 Free/delete strtok_r pointer before processing complete string?

问题 When trying to delete/free character ptr without being processed completely by strtok_r , its giving me stack trace error. I know that one cannot free/delete a strtok_r char ptr in a regular way, without completing the whole strings separation process by strtok_r func. Can anyone tell me how to free a char ptr, when its under process by strtok_r ? char *data = new char[temp->size()+1];//temp is of type string copy(temp->begin(),temp->end(),data); data[temp->size()]='\0'; count = 0; while

Tools for tracing calls to onActivityResult

阅读更多关于 Tools for tracing calls to onActivityResult

问题 What tools (log files, traces, etc) exist to debug calls to onActivityResult? The Android documentation says that onActivityResult is called when an activity you launched exits, giving you the requestCode you started it with, the resultCode it returned, and any additional data from it. The resultCode will be RESULT_CANCELED if the activity explicitly returned that, didn't return any result, or crashed during its operation.* I'm trying to debug a case where apparently none of those conditions

How can I get stack trace of a currently executing Task?

阅读更多关于 How can I get stack trace of a currently executing Task?

问题 I have a method that is called every time a new event to the application arrives. This method spins up a new task to process the event so we can return quickly. For example: public void HandleEvent(Event e) { Task.Run(() => { // Do something with e } } Sometimes processing that event takes a really long time and I want to find out why. One way I am thinking of doing this is to keep track of all currently executing such tasks and create a monitoring thread that keeps an eye for any tasks that

I would like the improve the most voted and non-accepted answer: https://stackoverflow.com/a/5028110/4934640 The problem I have this answer, is that it forces-me to use try...catch inside my Unit Tests.
