Complexity Analysis
Initialize parent and rank arrays for Union-Find structure.
For each number
i
from
threshold + 1
to
n
, connect
i
to its multiples by performing union operations.
For each query
[a, b]
, check if
a
and
b
have the same root in the Union-Find structure.
If they do, they are connected; otherwise, they are not.
