Same First Last Element

Background

(No specific background)

Problem Description

Given two integer arrays, $a$ and $b$, return true if they have the same first element or they have the same last element. Both arrays will be length $1$ or more.

Input Format

Input is given from standard input in the following format.

First line: Space-separated integers representing elements of array $a$. Second line: Space-separated integers representing elements of array $b$.

Output Format

Output to standard output in the following format.

Output true if the condition is met; otherwise, output false.

Sample

1 2 3
7 3

true

1 2 3
7 3 2

false

1 2 3
1 3

true

Sample Explanation

Sample 1: The first element of array $a$ is $1$, and the last element is $3$. The first element of array $b$ is $7$, and the last element is $3$. Since their last elements are the same (both $3$), it returns true. Sample 2: The first element of array $a$ is $1$, and the last element is $3$. The first element of array $b$ is $7$, and the last element is $2$. The first elements are different, and the last elements are also different, so it returns false. Sample 3: The first element of array $a$ is $1$, and the last element is $3$. The first element of array $b$ is $1$, and the last element is $3$. Since their first elements are the same (both $1$), it returns true.

Constraints

For each test case: Time limit $1$ second, Memory limit $1024$ KiB. Both arrays $a$ and $b$ will be length $1$ or more.
