1, ABA problem ABA problem means that in a concurrent environment, assuming that the initial condition is a, when modifying data, it will be modified if it is found to be a. However, although we see a, there may be a change from a to B and B back to a. This a is not that A. even if the data is successfully modified, there may be problems Solu ...
