Get First Two Elements

Background

Congcong is currently learning about array operations. He encountered a task that requires extracting a specific number of elements from a given array.

Problem Description

Given an integer array of any length, return a new array containing its first $2$ elements. If the array is smaller than length $2$, use whatever elements are present.

Input Format

Input is given from Standard Input in the following format.

The input consists of a single line representing an integer array. Array elements are space-separated and enclosed in square brackets [].

Output Format

Output is to Standard Output in the following format.

The output consists of a single line representing a new integer array. Array elements are separated by commas and spaces, and enclosed in square brackets [].

Sample

[1 2 3]

[1, 2]

[1 2]

[1, 2]

[1]

[1]

Sample Explanation

• Sample 1: The original array is [1 2 3]. Its length is greater than $2$, so the first two elements [1, 2] are returned.
• Sample 2: The original array is [1 2]. Its length is equal to $2$, so the first two elements [1, 2] are returned.
• Sample 3: The original array is [1]. Its length is less than $2$, so all existing elements [1] are returned.

Constraints

Time limit: $1$ second, Memory limit: $1024$ KiB for each test case.
