void sleepSortHelper(int i) {
    this_thread::sleep_for(chrono::microseconds(i*10000));
    std::cout << i << " ";
}
void sleepSort(int *arr,int size) {

    for (int i = 0; i < size; i++)
    {
        std::thread t(sleepSortHelper,arr[i]);
        t.detach();
    }

}
void main() {

    sleepSort(arr, 7);
