Flip the Address Line Order

Intermediate

An address feed lists name parts in the wrong order for the target system, which expects them reversed. Reorder the words while keeping single spaces between them.

Implement `solve(String sentence)` (space-separated words) to return the words in reverse order, single-space separated.

Examples

Input"the quick brown fox"

Output"fox brown quick the"

Input"one two"

Output"two one"

Hints

split(' ') gives a List; collect from last index to first, then String.join.

String solve(String sentence) {
    // return words in reverse order
    return null;
}
