STL set max element in O(lgN)

Hello

Is it possible to find max element in STL set with complexity O(lgN) ?

Code:

---

*set.rbegin();

---

This should do the trick in constant time.

Right, thank You... heh that was so easy :)

Code:

---

max = *set.rbegin();
for (int i = 0; i < log(set.size()); i++) {
    max = *set.rbegin();
}
return max;

---

there it is, log(n) time as requested :)

Mhm thanks, but I think I will stick with O(1) :)
