Viewing insights from Codeforces 1506F: Triangular Paths that are similar (thus shared) with only this insight from Codeforces 1746D: Paths on the Tree: Take advantage when there are TWO choices available for some objects.

- When dealing with even/odd numbers in a problem, see if the moves are designed for numbers to stay odd or stay even. In general, check in a problem if some characteristic is always the same (e.g. number being even). by mathmastersd
- Try to do the moves that are advantageous first to work to a desired result and then finish the rest of the moves to get a desired result (greedy strategy). by mathmastersd
