Can you find the first date of log on for a platform given a list of users.
We are looking for a program that manages disjointed intervals of integers. E.g.: [[1, 3], [4, 6]] is a valid object gives two intervals. [[1, 3], [3, 6]] is not a valid object because it is not disjoint. [[1, 6]] is the intended result. Empty array [] means no interval, it is the default/start state. We want you to implement two functions: add(from, to) remove(from, to) Here is an example sequence: Start: [] Call: add(1, 5) => [[1, 5]] Call: remove(2, 3) => [[1, 2], [3, 5]] Call: add(6, 8) => [[1, 2], [3, 5], [6, 8]] Call: remove(4, 7) => [[1, 2], [3, 4], [7, 8]] Call: add(2, 7) => [[1, 8]] etc. =================
