Check for 10 or Sum is 10

Background

Congcong is currently learning basic logical judgments. Dawei gave him a simple task to determine if two numbers meet specific conditions.

Problem Description

Given two integers $a$ and $b$, return true if one of them is $10$ or if their sum is $10$. Otherwise, return false.

Input Format

Input is given from standard input in the following format.

a b

Output Format

Output to standard output in the following format.

true or false

Sample

9 10

true

9 9

false

1 9

true

Sample Explanation

For Sample 1, the input is $9$ and $10$. One of the numbers is $10$, so true is returned. For Sample 2, the input is $9$ and $9$. Neither number is $10$, and their sum $9+9=18$ is not $10$, so false is returned. For Sample 3, the input is $1$ and $9$. Neither number is $10$, but their sum $1+9=10$ is $10$, so true is returned.
