Leetcode 2534

There are 5 states involved, leetcode 2534. State can be transformed by folds, etc, elegantly although perhaps not with great performance. Have you tried solving the problem you referenced?

There is a long and thin painting that can be represented by a number line. Painting the same area multiple times will create an uneven painting so you only want to paint each area of the painting at most once. Create a boolean array to store whether each block has been painted. We can check each of these blocks, painting the unpainted ones we also keep count of how many blocks we paint because that's what the question asks for. In the worst case, we have to check every block on every day. Let n n n be the number of days up to and let m m m be the largest number that appears in the input up to This is not fast enough.

In this problem, there are n persons who want to enter or exit through a door. Each person can enter or exit through the door once, taking one second. We are given a non-decreasing integer array arrival of size n , where arrival[i] is the arrival time of the i th person at the door. Also, there is an array state of size n , where state[i] is 0 if person i wants to enter through the door or 1 if they want to exit through the door. The main goal is to find an array answer of size n where answer[i] is the second at which the i th person crosses the door, considering various rules regarding entering and exiting the door. We can use two pointers approach for solving this problem.
