1. You can sort the query if offline!
2. Don't bring the dp remaining state when dfsing on DP on Tree.
3. Try to reverse (Think from the back) if you stuck.
4. Be careful when submitting Div. 2 D-F, dont waste it on stupid WAs.
5. Try to reduce a problem, think of it when you're making subtasks
   like when problemsetting.
