Problem:
Handsel Alice and Brown are brothers in a family and each receives pocket money in celebration of the coming year. They are very close and share the total amount of the money fifty-fifty. The pocket money each receives is a multiple of 1,000 yen. Write a program to calculate each one’s share given the amount of money Alice and Brown received. Input The input is given in the following format.  a  b  A line of data is given that contains two values of money: a (1000 ≤ a ≤ 50000) for Alice and b (1000 ≤ b ≤ 50000) for Brown. Output Output the amount of money each of Alice and Brown receive in a line. Sample Input 1 1000 3000 Sample Output 1 2000 Sample Input 2 5000 5000 Sample Output 2 5000 Sample Input 3 1000 2000 Sample Output 3 1500
