### Question:
ChordHelper { public boolean firstStringLeast(Chord chord) { int[] frets = chord.getFrets(); return frets[frets.length - 1] == chord.getLeastFret(); }  int[] getBarreChordData(Chord chord); boolean firstStringLeast(Chord chord); int getWithFirstString(Chord chord); int getMaxUnClosedString(Chord chord);  }### Answer:
@Test public void firstStringLeast() throws Exception { assertThat(mChordHelper.firstStringLeast(mChords.get(0)), is(false)); assertThat(mChordHelper.firstStringLeast(mChords.get(1)), is(true)); assertThat(mChordHelper.firstStringLeast(mChords.get(2)), is(false)); assertThat(mChordHelper.firstStringLeast(mChords.get(3)), is(true)); }
