, a hunger-like phenomenon will occur and the thread will stop.No Wait (wait-free)No lock requires only one thread to complete the operation within a finite step, while no waiting is further extended on a lock-free basis. It requires all threads to be completed in a limited number of steps, so that they do not cause hunger problems. If you limit the upper limit of this step, you can further decompose the no wait to have no waiting and the number of threads regardless of the few, the difference b
