Nearest to 10

Background

Congcong is learning how to compare numbers. He wants to find out which of two given numbers is closer to a specific target value.

Problem Description

Given 2 int values, return whichever value is nearest to the value 10, or return 0 in the event of a tie. Note that Math.abs(n) returns the absolute value of a number.

Input Format

Input is given from standard input in the following format.

Two integers $a$ and $b$.

Output Format

Output is printed to standard output in the following format.

An integer representing the value nearest to 10, or 0 if tied.

Sample

8 13

8

13 8

8

13 7

0

Sample Explanation

Sample 1: The absolute distance of $8$ from $10$ is $|8 - 10| = 2$. The absolute distance of $13$ from $10$ is $|13 - 10| = 3$. $8$ is closer to $10$, so $8$ is returned.

Sample 2: The absolute distance of $13$ from $10$ is $|13 - 10| = 3$. The absolute distance of $8$ from $10$ is $|8 - 10| = 2$. $8$ is closer to $10$, so $8$ is returned.

Sample 3: The absolute distance of $13$ from $10$ is $|13 - 10| = 3$. The absolute distance of $7$ from $10$ is $|7 - 10| = 3$. Both are equally distant from $10$, so $0$ is returned.

Constraints

Time limit: $1$ second, Memory limit: $1024$ KiB for each test case.
