Switch to Latest with SwitchMap

Create a Flux of "search-1", "search-2", "search-3" (simulating user typing). Use switchMap to process only the latest emission. Each should transform to "Results for: <query>". Print results.

switchMap cancels previous inner publishers when a new element arrives.

Expected

switchMap cancels previous inner publishers when a new element arrives.

Why this works

switchMap() cancels the previous inner publisher whenever a new element arrives from the outer publisher. This is the ideal pattern for search-as-you-type where you only care about the latest query's results.

Expected output

Results for: search-1
Results for: search-2
Results for: search-3
