Isolate the Even Batches

Basic

A batch processor only handles even-numbered batch IDs. Filter a list of IDs down to just the even ones, keeping their original order.

Implement `solve(List<Integer> nums)` to return only the even values, in their original order.

Examples

Input[1, 2, 3, 4, 5, 6, 7, 8]

Output[2, 4, 6, 8]

Input[1, 3, 5]

Output[]

Hints

Math.mod(n,2)==0 detects even numbers; add() preserves order.

List<Integer> solve(List<Integer> nums) {
    // return only the even values
    return null;
}
