My whole project was wiped out by visual studio… I was coding a website with flask in Visual Studio 2022 and one moment all of my files was wiped out – a whole week’s work. I could at least roll back most of my work, but how is this possible? Are there any logs I ..
I need to split an MxN matrix into N parts with an even number of rows in each part. Moreover, the last part will be too much if the matrix is odd. But I don’t know which algorithm I should use. Can’t figure out how to do this. Tell me please For example: we have ..
I’m a high school student and my teacher recently gave us a piece of homework, he said we can make basically any type of project until the end of the semester. I’m currently working on making ultimate tic tac toe, but before the board itself appears, I want to put up a few flags as ..
I was trying to attempt this question on Leetcode and got a TLE. There are 3 functions printZero, printEven, printOdd, which are given to 3 different threads. printZero only should print 0. printOdd should print 1, 3, 5, 7, … printEven should print 2, 4, 6, 8, … We should manage the code in such ..
I apologize if this is a duplicate of any question. I’m trying to code a function that finds a key for me. I have two classes declared in separate header files. I’m having trouble in the find function. Class Table is declared in htable.h as such: template<typename X, typename Y> class Table{ public: X key; ..
I’m having problems when trying to run threads with class methods. Ex: #include "p2p/p2pServer.h" #include <stdio.h> #include <stdlib.h> #include <thread> int main() { p2pServer server; std::thread listener(server.listenPeers()); std::thread connector(server.connectPeers()); listener.join(); connector.join(); } p2pServer is a class that has two functions: listenPeers and connectPeers, twice are int functions. My objective is to run that two functions ..
I am currently attempting to rebuild and update a Project written in Rust (more specifically it’s an SKSE64 plugin for Skyrim: https://github.com/lukasaldersley/sse-mod-skyrim-search-se forked from qbx2) The last problem I’m facing is the library now requires a struct to be exported from our library for version checking. I have attempted many probably stupid ways to implement ..
I’m trying to run openrgb [0] as root to be able to detect usb devices, as README says.

Consider: [1] int *func(){ int a[10]; //… return a; } int main(){ int* a = func(); } //在函数里开数组后往main函数回传指针 [2] void func(int a*){ //… } int main(){ int a[10]; func(a); } //在main函数开个数组后传实参到函数里 Two programs can define an array a and use it. Which one is better? Why?在内存分配和性能上有啥区别?更推荐哪种方式? Source: Windows Que..
i’m trying to initialize a defined section in my DRAM/IRAM with some pre-defined data. For that purpose, I defined a section "my_section" in the memory map file, at some fixed address. dram0_0 : C : 0x5ffd0400 – 0x5ffdb70f : .my_section.rodata …. Then i defined a struct, with couple of fields, and the initialization list struct ..
