Constrained optimization for the second problem - can create a function.

Not defending Fox, but Bongino stated many times that Fox wanted him to stay on the network, but he decided to leave to reduce his crazy work schedule. They did offer him a final sign-off show but he declined and opted to explain his move on his podcast and radio show. Tucker obviously WAS fired.

Letting dp[i][j] be the number of points you can cover placing an interval that ends at position i with j intervals used so far, you can do it in O(nk + nlog(n)) (where k is the number of intervals) with prefix maximums. Not sure if there's a generic O(n) or O(nlog(n)) solution.

Can you make a video about how you became so good in such a short time. How long did you use to practice for? What are your learning methods?

[@arinroday302]

WTF, stop asking these questions, you can't become good in short time. It takes multiple years. He answered this question before: He learnt from USACO training.
