runtime

问题 I'm currently working on this project and the main page takes nearly 5 whole minutes to load. I've been trying to reduce the runtime, but I'm still new to programming and I'm not too familiar with pthreads, but I was told pthreads wouldn't work with this. Can someone help me figure out how to run this code faster and stop Chrome from killing the processor? Also I know my PHP code is a bit messy, was planning on cleaning it up later, but the little bits of PHP code are around lines 0, 270, 420

问题 I want to implement same simple generic conversion method but on runtime I am getting an error. So the scenario is quite simple. I have same service that return me list of items of type External. I have my own WrapperExternal class that simply wrap this class and expose some additional functionality to it. I have some another set of classes that inherit from WrapExternal and add different functionalities. I want to create generic method that accept list of External list items and return list

问题 I'm trying to figure out the runtime of an algorithm. It is a sort which works by dividing the problem up into sets of 2/3's (it's the CLR sort). I'm having some trouble coming up with it, this is what I have: T(n)=3T([2n]/3)+1 (the 1 is because aside from the recursive calls, there is one exchange which may or may not be made. Assuming it is done, it is still only a constant cost.) T(n)=3T([2([2n]/3+1)]/3+1)+1 T(n)=3T([2([2([2n]/3+1)]/3+1)]/3+1)+1 T(n)=3T([2([2([2([2n]/3+1)]/3+1)]/3+1)]/3+1)

问题 We have an application that have many components on the forms (panels, tabs, edits, comboboxes, etc...). But depending on the user profile, most of them could be filled automatically and/or not be visible. So, users could do their work faster. The question: Is there any easier way to create, position, change ownership etc, at runtime? I would like to create 2 .dfm files for a given unit and then have something to tell the application what .dfm to use. Like: "Hey! User is advanced, use the

问题 If I define my own comparator for the generic HashSet<T> in System.Collections.Generic , and its runtime is O(1), is the lookup time of the hashset still O(1)? I would think no just because there doesn't appear to be a way to set the comparator. 回答1: The reason that the lookup time of a regular hashset is O(1) is because it uses open addressing to place objects into the array, so that won't change even if you use your own comparator. 回答2: In its best case it will have a insertion of amortised

问题 I need to calculated the runtime of a hash insertion. i have been using clock to do the time but i keep ending up with zero. Is there any certain way that would be the most efficient? This is my code for it so far: cout << "Testing chaining probing...\n"; HashTable_chaining ChainingHT( ITEM_NOT_FOUND, 101 ); int i = 0; while(i != DataArray.size()) { clock_t tStart = clock(); ChainingHT.insert(DataArray[i]); cout<<"Time taken:"<<(double)(clock() - tStart)/100000<<endl; if(i != NULL) {

问题 Is it possible to get Objects' memory address at runtime? For a certain c++ project, is it possible to track all objects' information, including memory address at runtime, lifetime and the counts of load & store? 来源： https://stackoverflow.com/questions/38527218/getting-the-memory-address-of-all-objects-at-runtime-in-llvm

问题 What is the algorithmic runtime of Python 2.7's isDisjoint(other) method for sets? Is it faster than simply doing intersection(other) and then checking len()>0 of that returned intersection? 回答1: The complexity in both cases is going to be O(min(len(s), len(t)) . The only difference is that intersection creates a new set of all matched items and isdisjoint simply returns a boolean and can short-circuit as soon as a match is found. Example that short-circuits right away: >>> s1 = set(range(10*

问题 I'm running Android Studio 3.2.1, 32-bit on Windows Vista with JRE 1.8.0 x86 and JetBrains s.r.o OpenJDK. My default app seems to build fine although Gradle takes some time, but when I run it, it prompts me with an "Edit Configurations..." dialog and then says "Click the + button to create a new configuration based on default settings." from which I select "Android App" on the left, but then where the "Module:" field is I can only select "" so I cannot run my app. The error I get at the

问题 I am using gzip utilities in windows machine. I compressed a file and stored in the DB as blob. When I want to decompress this file using gzip utility I am writing this byte stream to process.getOutputStream. But after 30KB, it was unable to read the file. It hangs there. Tried with memory arguments, read and flush logic. But the same data if I try to write to a file it is pretty fast. OutputStream stdin = proc.getOutputStream(); Blob blob = Hibernate.createBlob(inputFileReader); InputStream
