C++

In 2016, I proposed a problem about trying to take three rectangles and seeing if it was possible to combine them to form a square. It got accepted. Please implement this function instead.

bool f(int n)

You may assume $1 \le n \le 10^6$ ~1 \le n \le 10^6~.

Any tips on how to not TLE. I think my solution has a O(n + sqrt(n)) time complexity, which should be well under the time limit.

Hint: Aim for $\mathcal O(\log n)$ ~\mathcal O(\log n)~. (Solution)
