Cell Serialization to BoC

Cell c1 = CellBuilder.beginCell().storeUint((long) Math.pow(2, 25), 26).endCell();

Cell c2 = CellBuilder.beginCell()
                        .storeUint((long) Math.pow(2, 37), 38)
                        .storeRef(c1)
                     .endCell();

Cell c3 = CellBuilder.beginCell().storeUint((long) Math.pow(2, 41), 42).endCell();
Cell c4 = CellBuilder.beginCell().storeUint((long) Math.pow(2, 42), 44).endCell();
Cell c5 = CellBuilder.beginCell()
                        .storeAddress(Address.parseFriendlyAddress("0QAljlSWOKaYCuXTx2OCr9P08y40SC2vw3UeM1hYnI3gDY7I"))
                        .storeString("HELLO")
                        .storeRef(c2)
                      .endCell();

log.info("c1 {}", c1.bits);

log.info("c3 {}", c3.bits);

Cell Deserialization from BoC

byte[] serializedCell5 = c5.toBocNew();
Cell dc5 = CellBuilder.beginCell().fromBoc(serializedCell5);
log.info("c5 deserialized:\n{}", dc5.print());

// output
c5 deserialized:
