Critical section recursion count

WebConsider the sequence (an)n ≥ 1 which satisfies the recurrence relation an = ∑n − 1i = 1ai. That is, each term of the sequence is the sum of all previous terms in the sequence. … In concurrent programming, concurrent accesses to shared resources can lead to unexpected or erroneous behavior, so parts of the program where the shared resource is accessed need to be protected in ways that avoid the concurrent access. One way to do so is known as a critical section or critical region. This protected section cannot be entered by more than one process or thread at a time; others are suspended until the first leaves the critical section. Typically, the crit…
