Given an unsorted LaTeX: \texttt{vector} vector and a number LaTeX: n n , what is the worst-case time complexity for finding the pair of integers whose sum is closest to LaTeX: n n , if you are not allowed to use any additional memory? For example, if you were given the vector LaTeX: \{12, 3, 17, 5, 7\} { 12 , 3 , 17 , 5 , 7 } and LaTeX: n = 13 n = 13 , you would return the pair LaTeX: \{5, 7\} { 5 , 7 } .

this seems to be in the wrong category. but i'll take some free points my dude

posting this in wrong category will result in people seeing it who won't know the answer.

which functions return a valid value without any arguments?

(-blank- and -blank- return a valid value without any arguments.)

1st -blank-

today

sqrt

count

2nd -blank-

round

now
