## Puzzle 12 - compress
## Puzzle 12 - pad_to


Compute [compress](https://numpy.org/doc/stable/reference/generated/numpy.compress.html) - keep only masked entries (left-aligned).
Compute pad_to - eliminate or add 0s to change size of vector.


```python
def compress_spec(g, v, out):
j = 0
for i in range(len(g)):
if g[i]:
out[j] = v[i]
j += 1

def compress(g: TT["i", bool], v: TT["i"], i:int) -> TT["i"]:
def pad_to_spec(a, out):
for i in range(min(len(out), len(a))):
out[i] = a[i]


def pad_to(a: TT["i"], i: int, j: int) -> TT["j"]:
raise NotImplementedError


test_compress = make_test("compress", compress, compress_spec, add_sizes=["i"])
test_pad_to = make_test("pad_to", pad_to, pad_to_spec, add_sizes=["i", "j"])
```
