Two important functions that convert pairlists to pairs of lists and vice versa are zip and unzip. implement a function zip that takes a pair xs#ys of two lists xs and ys (of the same length) and returns a pairlist, where the first field of each pair is taken from xs and the second from ys.

for example, {zip [a b c]#[1 2 3]} returns the pairlist [a#1 b#2 c#3].the function unzip does the inverse, for example {unzip [a#1 b#2 c#3]} returns [a b c]#[1 2 3]. give a specification and implementation of unzip. oz programming language

Ap practice - performance task response the ap create performance task asks you to write about an abstraction that you developed and wrote into your code. most of the time that means identifying a function or procedure you wrote to "manage complexity" in your program. here is the actual prompt from the create performance task: 2d. capture and paste a program code segment that contains an abstraction you developed individually on your own (marked with a rectangle). this abstraction must integrate mathematical and logical concepts. explain how your abstraction manage the complexity of your program. (must not exceed 200 words) below is a segment of code from an "under the sea" program with a rectangle drawn around a portion of the code identifying an abstraction. imagine that you wrote this and are composing an ap response about how this abstraction manages complexity. (note: ignore the requirement that the abstraction integrate "mathematical and logical concepts" for this practice response. just write about managing complexity). explain how the abstraction marked with the rectangle in the code above manage complexity of this program. write your response here submit

What statement best describes operating systems? it’s possible for modern computers to function without operating systems. most operating systems are free or very inexpensive. operating systems are managed by the computer’s microprocessor (cpu). operating systems manage the computer’s random access memory (ram).
