### Question:
TypeDecoder { @SuppressWarnings("unchecked") static <T extends Type> T decodeDynamicArray( String input, int offset, TypeReference<T> typeReference, long chainId) { int length = decodeUintAsInt(input, offset, chainId); BiFunction<List<T>, String, T> function = (elements, typeName) -> { if (elements.isEmpty()) { return (T) DynamicArray.empty(typeName); } else { return (T) new DynamicArray<>(elements); } }; int valueOffset = offset + MAX_BYTE_LENGTH_FOR_HEX_STRING; return decodeArrayElements(input, valueOffset, typeReference, length, function, chainId); }  static T decode(
            String input, int offset, TypeReference<T> typeReference,long chainId);  }### Answer:
