I just do not know how to use (tmp[::-1]) which was suggested at the hint to reverse the order, so could anyone help me please, thank you!

Lets suppose you have:

a = [1,2,3]

a = a[::-1]

now a is the first a but reverse.

Thank you, but if I did so it shows this message â€śIndexError: only integers, slices (`:`

), ellipsis (`...`

), numpy.newaxis (`None`

) and integer or boolean arrays are valid indicesâ€ť

so what am I supposed to do, or how to fix it?

Thank you for helping me, the problem was not in the way I use this thing â€ś[::-1]â€ť after your response, I tried to figure out where is the problem and I did, thank you.

Just a note of caution!: I have initially sorted in reverse order using `np.argsort(-np.array(similarity_l))`

which should be the same, right? apparently this caused some sort stability issues as I was not getting test cases pass at the very end in `approximate_knn`

(I was getting good results by my judgement when visually expecting tweets but grader wasnâ€™t happy).

Apparently, grader only would be happy if you do `argsort`

and then reverse the array.

hey bro how did you solve this issue?
