Find the disappearing numbers (LeetCode 448) | Full solution with examples | Study Algorithms

An integer array of size 'n' contains elements in the range of [ 1, n ] There may or may not be repeating numbers. You need to find the numbers that are disappeared from this range. In this video we explore the most straight forward way to approach this problem and then try to optimize it eventually. The video discusses an in-place solution that is both time and space efficient. All of this along with beautiful animations and visuals. The dry-run of code is also provided in JAVA.
