Jugaadu and Shruti are playing a turn-based block game. At the beginning of the game, several blocks are placed in pairs to form a tower. The players remove one block from the tower and place it on the top of the tower. The player who causes the tower to fall loses the game. Can you help Shruti in not losing the game?
1. Take one block from any level of the tower (except the one below an incomplete top level)
2. Place the block on the topmost level in order to complete it.
3. The game ends when the tower falls completely or if any block falls from the tower.
