### Question:
ByteSequenceRowObject { public static DittedBitSequence merge(List<ByteSequenceRowObject> rowObjects) { if (rowObjects == null || rowObjects.size() == 0) { return null; } List<DittedBitSequence> dittedSeqs = new ArrayList<>(); for (ByteSequenceRowObject currentRow : rowObjects) { DittedBitSequence currentSeq = new DittedBitSequence(currentRow.getSequence(), true); dittedSeqs.add(currentSeq); } DittedBitSequence currentMerge = dittedSeqs.get(0); for (int i = 1, max = dittedSeqs.size(); i < max; ++i) { currentMerge = new DittedBitSequence(currentMerge, dittedSeqs.get(i)); } return currentMerge; } ByteSequenceRowObject(String byteSequence, String disassembly, int numOccurences,
			double percentage); static List<ByteSequenceRowObject> getFilteredRowObjects(
			List<FunctionBitPatternInfo> unfilteredInfo, PatternType type,
			ContextRegisterFilter registerFilter, ByteSequenceLengthFilter lengthFilter); String getSequence(); String getDisassembly(); int getNumOccurrences(); double getPercentage(); static List<ByteSequenceRowObject> getRowObjectsFromInstructionSequences(
			List<FunctionBitPatternInfo> unfilteredInfo, InstructionSequenceTreePathFilter pathFilter,
			ContextRegisterFilter contextRegisterFilter); static DittedBitSequence merge(List<ByteSequenceRowObject> rowObjects);  }### Answer:
@Test public void testBasicMerge() { List<ByteSequenceRowObject> seqs = new ArrayList<>(); seqs.add(new ByteSequenceRowObject("554889e548", null, 1, 0.3)); seqs.add(new ByteSequenceRowObject("554889e553", null, 1, 0.3)); seqs.add(new ByteSequenceRowObject("554889e589", null, 1, 0.3)); DittedBitSequence lub = ByteSequenceRowObject.merge(seqs); String pattern = lub.getHexString(); assertEquals(pattern, "0x55 0x48 0x89 0xe5 ..0..0.."); assertEquals(lub.getNumUncertainBits(), 6); assertEquals(lub.getNumFixedBits(), 34); }
@Test public void testNullMerge() { assertEquals(null, ByteSequenceRowObject.merge(null)); }
@Test public void testEmptyMerge() { assertEquals(null, ByteSequenceRowObject.merge(new ArrayList<ByteSequenceRowObject>())); }
