Before revision:  In this paper, we improve the running times of their algorithms and consider new variants of STICK, where no ordering is given, STICK_A, and STICK_AB where the lengths of the sticks are given as input.
After revision:  In this paper, we improve the running time of their algorithm, and we solve STICK_A efficiently. Further, we consider variants of these problems where the lengths of the sticks are given as input.
