negative 10: -1234.056789
negative 3: -1234.057
additional : 1.01
Now, all criteria are met:

How to find the kth largest element in an unsorted array of length n in O(n)?
...∑i=floor(n/2) to n T(i)
<= cn + 2 (1/n) ∑i=floor(n/2) to n ai
and now somehow we have to get the horrendous sum on the right of the plus sign to absorb the cn on the left. If we just bound it as 2(1/n) ∑i=n/2 to n an, we get roughly 2(1/n)(n/2)an = an. But this is too big - there's no r...
