Status: OUT
Solutions eliminate unnecessary computation at two levels: mathematical reduction removes entire computational phases (closed-form replaces iteration), while early-exit pruning removes unnecessary iterations within remaining phases — together minimizing work from both above and below.
Mathematical reduction and early-exit pruning are complementary — one eliminates phases, the other truncates them
