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≤X,Y≤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.
