Understanding the Data Stream as Disjoint Intervals Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Given a data stream input of non-negative integers a1, a2, ..., an, summarize the numbers seen so far as a list of disjoint intervals. Implement the SummaryRanges class: SummaryRanges() Initializes the object with an empty stream. void addNum(int value) Adds the integer value to the stream. int[][] getIntervals() Returns a summary of the integers in the stream currently as a list of disjoint intervals [starti, endi]. The answer should be sorted by starti.
