You are asked to answer the queries that the sum of the endurance of a consecutive part of the battleship (1 <= N <= 100000) The second line contains N integers Ei, indicating the endurance value of each battleship secret weapon, which will decrease the endurance value of the battleships between the X-th and Y-th battleship The T=1 denoting the query of the commander which ask for the sum of the endurance value of the battleship
如下所示: public enum SpaceShip { SCOUT, CARGO, TRANSPORT, CRUISER, BATTLESHIP, MOTHERSHIP; public String SpaceShip s : values()) { System.out.println(s); } } } /* Output: Scout Cargo Transport Cruiser Battleship
