sorry, the maybe some mistake
`array<int> output = bitmap_remove(bitmap value, array<int> arr)`
should be like this:
`bitmap output = bitmap_remove(bitmap value, array<int> arr)`
and this function means eg:
we know a bitmap value contains some nums:
```
mysql [(none)]>select bitmap_to_string(bitmap_from_array([1,2,3,4,5]));
+-----------------------------------------------------------+
| bitmap_to_string(bitmap_from_array(ARRAY(1, 2, 3, 4, 5))) |
+-----------------------------------------------------------+
| 1,2,3,4,5
|
+-----------------------------------------------------------+
```
if the second param of arr is [1,2]
we wants the function bitmap_remove(value,arr) result of bitmap is only
contains (3,4,5)
I think you could refer some bitmap function in Doris like:
bitmap_contains....
