Understanding the Count Integers in Intervals Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Given an empty set of intervals, implement a data structure that can: Add an interval to the set of intervals. Count the number of integers that are present in at least one interval. Implement the CountIntervals class: CountIntervals() Initializes the object with an empty set of intervals. void add(int left, int right) Adds the interval [left, right] to the set of intervals. int count() Returns the number of integers that are present in at least one interval. Note that an interval [left, right] denotes all the integers x where left <= x <= right.
