Collapse the Duplicate Record Ids

Basic

A trigger collects record Ids that may repeat across rows. Before a query you need the distinct Ids only.

Implement `solve(List<Id> input)` to return a Set of the unique Ids.

Examples

Input[001...1, 001...1, 001...2]

Output{001...1, 001...2}

Input[001...3]

Output{001...3}

Hints

A Set built from a List deduplicates automatically.

Anonymous Apex

Set<Id> solve(List<Id> input) {
    // return the unique Ids
    return null;
}

Your code runs in a secure sandbox against multiple hidden test cases. The problem is solved only when every test passes. Each run is isolated and any data changes are rolled back automatically.
