Problem:
 Score: 100 points    Problem Statement There is a train going from Station A to Station B that costs X yen (the currency of Japan).  Also, there is a bus going from Station B to Station C that costs Y yen.  Joisino got a special ticket. With this ticket, she can take the bus for half the fare if she travels from Station A to Station B by train and then travels from Station B to Station C by bus.  How much does it cost to travel from Station A to Station C if she uses this ticket?      Constraints  1 \leq X,Y \leq 100  Y is an even number.  All values in input are integers.         Input Input is given from Standard Input in the following format:  X  Y       Output If it costs x yen to travel from Station A to Station C , print x .        Sample Input 1 81 58      Sample Output 1 110   The train fare is 81 yen.  The train fare is 58 ⁄ 2=29 yen with the 50 % discount.   Thus, it costs 110 yen to travel from Station A to Station C .       Sample Input 2 4 54      Sample Output 2 31
