functional programming - Difference between function, method, routine . . . Routine and subroutine Those words have mostly disappeared in modern languages They were used in older programming languages See also this related question: What's the technical definition for "routine"? Subprogram A subprogram is a part of a program that could be consider a program on its own
computer architecture - Is the reason for a stack to decrease the size . . . $\begingroup$ If you would like to elaborate in your answer on why that is the case, feel free I can see how stack provides return address when doing nested subroutine calls (otherwise a single register is enough, but for arbitrary many levels deep nested calls), and also when needing different arguments depending on what calls the subroutine
Can a processor without stack pointer registers, have a subroutine . . . It cannot have subroutine call instruction ; It cannot have nested subroutines call; Interrupts are not possible; All subroutine calls and interrupts are possible ===== I think answer is 2 Reason- Because in nested subroutine calls, we push old subroutines into stack and point most recent call with stack pointer Please, explain which is the
Probabilty that quicksort partition creates an imbalanced partition Recall the Partition subroutine employed by the QuickSort algorithm, as explained in lecture What is the probability that, with a randomly chosen pivot element, the Partition subroutine produces a split in which the size of the smaller of the two subarrays is ≥α times the size of the original array? The answer is 1-2*α
Why are special instructions used to implement system calls? Why not . . . System calls could be done, and have been done, with normal (normal enough) call instructions However, the operation wouldn't be a normal call: the privilege level changes, and it is unsafe to allow calling arbitrary offsets (which might not be the entrypoint of a subroutine) with a lot of privileges So there should be some mechanism that
