Your computer engineering instructor gave you a simple task:

Write a program to find the integer mean of three integers A, B, C.

Since you think this is too easy a task for your programming prowess, you've decided to make life more interesting... by computing this simple mean in assembly.

Input Specification

The first line of input will contain 3 space-separated integers A, B, C (0 \le A, B, C \le 10).

Output Specification

The integer mean of the three integers.

Sample Input

1 2 4

Sample Output



To use libc in NASM, the first line of your program should be ; libc. For all others, it should be ; features: libc.

Language Constraints

Because Assembly (ARM) runs under qemu, it is allocated 0.5s and 4096kb of RAM.

    For Help :

    PHP version : <?php $handle = fopen ("php://stdin","r"); $line = fgets($handle); $z = explode(' ',$line); $t = $z[0]+$z[1]+$z[2]; $t2 = $t/3; echo intval($t2); ?>

    For some reason, I'm getting a floating point exception when I try to divide, even though my numbers are correct. Does the div command work a different way than I think? The way I understand it, if I mov bl, 3 and div bl, it would divide ax by bl and store the quotient in al.
