Suppose you’re to organize a summer sports camp, and the
following problem comes up. the camp is supposed to have at least
506

one counselor who’s skilled at each of the n sports covered by the camp
(baseball, volleyball, and so on). they have received job applications from
m potential counselors. for each of the n sports, there is some subset
of the m applicants qualified in that sport. the question is: for a given
number k < m, is it possible to hire at most k of the counselors and have
at least one counselor qualified in each of the n sports? we’ll call this the
efficient recruiting problem.
show that efficient recruiting is np-complete.

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
