The best solution to the question is not very straightforward and easy to forget
It's easy to miss the best solution without realizing it.
⚪ No blocker to resolve it using the best solution but
may need some time (>2 mins) to think
may miss a simpler way of implementing
getting issues due to errors not related to the algorithm itself.
it feels tricky, and I’m unsure I could solve it again next time.
