Extract First N Even Numbers

Background

Congcong is learning array operations and has encountered a task that requires filtering specific elements from an integer array.

Problem Description

Given an array of positive integers, and an integer $count$. Return a new array of length $count$ containing the first $count$ even numbers from the original array. It is guaranteed that the original array will contain at least $count$ even numbers.

Input Format

Input is given from standard input in the following format.

A single line containing several positive integers. The first part represents the elements of array $arr$ (space-separated), and the last integer represents $count$.

Output Format

Output is printed to standard output in the following format.

A single line representing the new array, containing the first $count$ even numbers from the original array. Array elements are separated by commas and spaces, and enclosed in square brackets [].

Sample

3 2 4 5 8 2

[2, 4]

3 2 4 5 8 3

[2, 4, 8]

6 1 2 4 5 8 3

[6, 2, 4]

Sample Explanation

Sample 1: Input array [3 2 4 5 8] and $count = 2$. The even numbers in the original array are $2, 4, 8$ in order. Taking the first $2$ even numbers yields [2, 4]. Sample 2: Input array [3 2 4 5 8] and $count = 3$. The even numbers in the original array are $2, 4, 8$ in order. Taking the first $3$ even numbers yields [2, 4, 8]. Sample 3: Input array [6 1 2 4 5 8] and $count = 3$. The even numbers in the original array are $6, 2, 4, 8$ in order. Taking the first $3$ even numbers yields [6, 2, 4].
