so the first bug i said was that lines 7 to 9 are not needed, since they remove half the ids and scores, which is not required in the question

the other bug was line 13. it indexes rows but it should index columns

whats the other bug?

the question says the three bugs r related to boolean masking, sorting logic and array indexing. so maybe something to do with sorting logic?

i cant find it tho

[tardy cosmos]

have you tried simply running some code? then tweak some stuff and run again
usually it helps out quite a bit

[burnt oak]

yep i did after adding the bug fixes

and it works

[tardy cosmos]

for example,

>>> import numpy as np
>>> a = np.arange(12).reshape(3, -1)
>>> a
array([[ 0,  1,  2,  3],
       [ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])
>>> a[:, 1:3]
array([[ 1,  2],
       [ 5,  6],
       [ 9, 10]])
>>> a[1:3, :]
array([[ 4,  5,  6,  7],
       [ 8,  9, 10, 11]])
```then note the sorting part

[burnt oak]

but there doesnt seem to be a 2nd bug

[tardy cosmos]

so is the issue that after you fixed 2 bugs it seems to run fine, but there should be 3 bugs?

[burnt oak]

yes

i commented this out

and rewrote this so it indexes columns

and after printing i get

[tardy cosmos]

hm
looks fine to me too
maybe the original problem just considers one of your found bugs as 2?

[burnt oak]

maybe this bug is 2 bugs

the question states tho

the script contains three bugs related to boolean masking, sorting logic, and
incorrect array indexing

so it must be something related to sorting logic?

[tardy cosmos]

but you can argue that "incorrectly re-ordering the rows instead of columns" is the sorting bug
like you can cut it a lot of ways

as to what constitutes a singular bug

[burnt oak]

hmm yh

so then what would the incorrect array indexing bug be then

[tardy cosmos]

you can say it's also the same line
i.e. the sorting bug is due to incorrect indexing

or like up above at the mask area
"you shouldn't remove people through indexing" or smthn
again I think there's multiple ways you can cut it

[burnt oak]

ok yh cool

so esentially there could be 2 bugs in 1

[tardy cosmos]

yeah that's what I mean
maybe what you consider 1 bug, the problem considers 2
resulting in your situation

[burnt oak]

thanks for ur help

[burnt oak]

could i say that once i fix this (i.le comment out the masking)

it also fixes

sorted_indices = np.argsort(ID)

which is the sorting logic bug, as np.argsort orriignally takes in the masked IDs?

[tardy cosmos]

like sure ig
