Check Array First or Last Element

Background

Congcong is learning basic array operations. He encountered a problem that requires checking specific elements of an array.

Problem Description

Given an array of integers, return true if the number $6$ appears as either the first or last element in the array. The array will be of length $1$ or more.

Input Format

Input is given from standard input in the following format.

A single line containing an array of integers, with elements separated by spaces.

Output Format

Output is printed to standard output in the following format.

Output true if $6$ appears at the beginning or end of the array; otherwise, output false.

Sample

1 2 6

true

6 1 2 3

true

13 6 1 2 3

false

Sample Explanation

Sample $1$: The last element of the array is $6$, so true is returned. Sample $2$: The first element of the array is $6$, so true is returned. Sample $3$: The first element of the array is $13$, and the last element is $3$. Neither is $6$, so false is returned.

Constraints

Time limit: $1$ second per test case. Memory limit: $1024$ KiB per test case.
