10K++ people passed. You should opt for an O(N) approach, O(N^2) with more than 1 loop iteration may time out.

Unfortunately, 652 is not a perfect square (sqrt(652) ≈ 25.5342907), whereas 625 is (625 = 25 * 25). The correct answer to return here is 625.

Your code fails to take into account when only the first letter of the word is in lowercase & the rest is uppercase:

tBAWJUB becomes TBAWJUB => Technically not an acronym, but first letter of the first word of a sentence should be uppercased.

yes

As you iterate through your list (text here),
you are conditionally removing elements from the list.
This will result in unpredictable behaviour.

If removal is necessary, iterate over a copy of the list
or use techniques such as iterating backwards
to avoid index shifting issues.
