Array First Last Equal

Background

Congcong is learning about arrays, and Dawei has given him a simple task to check a property of an array.

Problem Description

Given an array of integers. Return true if the array's length is $1$ or more, and its first element is equal to its last element; otherwise, return false.

Input Format

Input is given from standard input in the following format.

A single line containing several space-separated integers, representing the elements of the array.

Output Format

Output is printed to standard output in the following format.

Output true if the array satisfies the condition; otherwise, output false.

Sample

1 2 3

false

1 2 3 1

true

1 2 1

true

Sample Explanation

• Sample 1: The array is [1 2 3]. The array length is $3$, which is greater than or equal to $1$. The first element is $1$, and the last element is $3$. Since $1 \neq 3$, the output is false.
• Sample 2: The array is [1 2 3 1]. The array length is $4$, which is greater than or equal to $1$. The first element is $1$, and the last element is $1$. Since $1 = 1$, the output is true.
• Sample 3: The array is [1 2 1]. The array length is $3$, which is greater than or equal to $1$. The first element is $1$, and the last element is $1$. Since $1 = 1$, the output is true.
