Solution: Try Different Synchronization Techniques

#include <iostream>
#include <atomic>
#include <thread>
#include <vector>
std::vector<int> mySharedWork;
std::atomic_flag atomicFlag;
void waitingForWork(){
    std::cout << "Waiting " << std::endl;
    atomicFlag.wait(false);
    mySharedWork[1] = 2;
    std::cout << "Work done " << std::endl;
}
void setDataReady(){
    mySharedWork = {1, 0, 3};
    std::cout << "Data prepared" << std::endl;
    atomicFlag.test_and_set();
    atomicFlag.notify_one();
}
int main(){
    std::cout << std::endl;
    std::thread t1(waitingForWork);
    std::thread t2(setDataReady);
    t1.join();
    t2.join();
  
    for (auto v: mySharedWork){
        std::cout << v << " ";
    }
      
    std::cout << "\n\n";
}
