As with stacks, we can also use a single-linked list to implement queue ADT. Similarly, for efficiency reasons, we will use the first (last) node of the single-linked list as the first (last) node of the queue?? This avoids the inefficiency of the

The view v $ session_wait can be used to view the current wait events of the system and the information about the resources corresponding to the wait events, so as to determine the type of the bottleneck and its objects. The P1, P2, and P3 values of
