### Question:
Util { public static int fastDivCeiling(final int numerator, final int denominator) { return ((numerator - 1) / denominator) + 1; }  static Address signatureToAddress(final Signature seal, final Hash dataHash); static Address publicKeyToAddress(final PublicKey publicKey); static Address publicKeyToAddress(final Bytes publicKeyBytes); static int fastDivCeiling(final int numerator, final int denominator);  }### Answer:
@Test public void testFastDivCeil() { assertThat(Util.fastDivCeiling(0, 3)).isEqualTo(1); assertThat(Util.fastDivCeiling(1, 3)).isEqualTo(1); assertThat(Util.fastDivCeiling(2, 3)).isEqualTo(1); assertThat(Util.fastDivCeiling(3, 3)).isEqualTo(1); assertThat(Util.fastDivCeiling(4, 3)).isEqualTo(2); assertThat(Util.fastDivCeiling(5, 3)).isEqualTo(2); assertThat(Util.fastDivCeiling(6, 3)).isEqualTo(2); assertThat(Util.fastDivCeiling(7, 3)).isEqualTo(3); }
