### Flatn Lattice Reduction Example

Source: https://github.com/zksecurity/flatn/blob/master/README.md

Demonstrates how to use the `flatn.reduce()` function to perform lattice reduction on a given lattice basis. It shows how to define a lattice and print the reduced basis. It also illustrates how to control reduction quality using parameters like `delta`.

```python
import flatn

# define a lattice as a list of basis vectors
lattice = [
    [1, 0, 331, 303],
    [0, 1, 456, 225],
    [0, 0, 628, 0],
    [0, 0, 0, 628]
]

# derform lattice reduction
reduced_basis = flatn.reduce(lattice)

print(reduced_basis)

# You can also control the reduction quality with parameters:
# - alpha: higher means more reduced
# - rhf: target root Hermite factor
# - delta: LLL parameter (between 0.25 and 1.0)
# - logcond: maximum allowed log of condition number

# For example, specifying delta:
reduced_basis = flatn.reduce(lattice, delta=0.99)
```
