Even Squares

Given a list of integers, return a new list containing the squares of only the even numbers. An integer \(n\) is even if \(n \equiv 0 \pmod{2}\). If there are no even numbers, the result is an empty list.

You need to read the input from standard input and write the output to standard output. The order of squared even numbers should be the same as their original order in the input.

inputFormat

The input consists of a single line containing space-separated integers. The line could be empty, which represents an empty list.

outputFormat

Output a single line of space-separated integers which are the squares of the even numbers from the input. If there are no even numbers, output an empty line.
