Explanation and Report:

In ThreadA and ThreadB, while loops are introduced to check the value of step before proceeding with certain calculations. These loops will cause the threads to yield until the required step is reached.

The main method now includes a loop to run the threads for a high number of iterations (set by the iterations variable). Before each iteration, step is set to 0 to reset the synchronization.
