Describe a Θ(nlgn) algorithm that, given a set S of n integers and another integer ,determines whether or not there exist two elements in S whose sum is exactly x.

i found two solutions,   n = 2 • ± √3 = ± 3.4641

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
