### Question:
Part03Filtering { Flux<Integer> ignoreDuplicates(Flux<Integer> flux) { return flux.distinct().log(); }    }### Answer:
@Test public void ignoreDuplicates() { Flux<Integer> flux = workshop.ignoreDuplicates(Flux.just(1, 1, 2, 2, 3, 4)); StepVerifier.create(flux) .expectNext(1, 2, 3, 4) .verifyComplete(); }
