| <h2>Combine - BinaryCombineFn Lambda</h2> |
| <p> |
| BinaryCombineFn is used for implementing combiners that are more easily expressed as binary |
| operations. |
| </p> |
| <p> |
| Since Beam v2.13.0, you can also use lambda or method reference in order to create the |
| BinaryCombineFn. |
| </p> |
| <p> |
| <b>Kata:</b> Implement the summation of BigInteger using lambda or method reference. |
