Shared Digit

Background

Congcong has recently been studying the properties of numbers. He is curious to know if there's an interesting connection between two two-digit numbers.

Problem Description

Given two integers, each in the range $10$ to $99$, return true if there is a digit that appears in both numbers, such as the $2$ in $12$ and $23$. Otherwise, return `false$. (Note: integer division, e.g.,$n/10$, gives the left digit (tens place) while the modulo operation, e.g.,$n%10$, gives the right digit (ones place).)

Input Format

Input is given from standard input in the following format.

a b

Output Format

Output is given to standard output in the following format.

result

Sample

12 23

true

12 43

false

12 44

false

Sample Explanation

For the first sample, the two input numbers are $12$ and $23$. The number $12$ contains digits $1$ and $2$. The number $23$ contains digits $2$ and $3$. Since both numbers contain the digit $2$, the output is true.

Constraints

Time limit: $1$ second, Memory limit: $1024$ KB for each test case. The two input integers $a, b$ satisfy $10 \le a, b \le 99$.
