Func5(n) 1 s=0; 2 i=6; 3 while (i < n^(5/2)) do 4 j=4; 5 while (j < 5i) do 6 s=s + i - j; 7 j=j + 9 ; 8 end 9 i=4 * i ; 10 end 11 return (s);

So far I got the upper bound for this function is O(n^(5/2)log(n)) and I am not sure if or not this is the closest upper bound we can get. And I have no clue how to show the lower bound with the same function.
