Exercise 4.4.6: wait/signal vs wait/notify. info about a different version of a monitor, developed for the programming language mesa, replaces the primitive "signal" with "notify", which does not block the invoking process on the urgent queue but allows the process to finish the current function. as a result, a process is able to execute multiple "notify" statements before exiting a function. two processes, p1 and p2, call the function f() in the following monitor and since x < 0, both become blocked on c. a process p3 calls g() and notifies both p1 and p2 that x is now greater than 0. monitor m { x = -1 f() { if (x < 0) c. wait x = h(x) } g() { x = 1 c. notify c. notify } (a) what could go wrong with this code and yield incorrect results? (b) how could the program be modified to avoid the problem?

Assume that minutes is an int variable whose value is 0 or positive. write an expression whose value is "undercooked" or "soft-boiled" or "medium-boiled" or "hard-boiled" or "overcooked" based on the value of minutes. in particular: if the value of minutes is less than 2 the expression's value is "undercooked"; 2-4 would be a "soft-boiled", 5-7 would be "medium-boiled", 8-11 would be "hard-boiled" and 12 or more would be a "overcooked".
