### Question:
Part5ResilienceResponsive_Optional { @Complexity(HARD) public static Publisher<Integer> provideSupportOfContinuation(Flux<Integer> values) { return values; }  @Complexity(HARD) static Publisher<Integer> provideSupportOfContinuation(Flux<Integer> values); @Complexity(HARD) static Publisher<Integer> provideSupportOfContinuationWithoutErrorStrategy(Flux<Integer> values, Function<Integer, Integer> mapping);  }### Answer:
@Test public void provideSupportOfContinuationTest() { Flux<Integer> range = Flux.range(0, 6) .map(i -> 10 / i); StepVerifier.create(provideSupportOfContinuation(range)) .expectSubscription() .expectNextCount(5) .expectComplete() .verify(); }
