Understanding the Group the People Given the Group Size They Belong To Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
There are n people that are split into some unknown number of groups. Each person is labeled with a unique ID from 0 to n - 1. You are given an integer array groupSizes, where groupSizes[i] is the size of the group that person i is in. For example, if groupSizes[1] = 3, then person 1 must be in a group of size 3. Return a list of groups such that each person i is in a group of size groupSizes[i]. Each person should appear in exactly one group, and every person must be in a group. If there are multiple answers, return any of them. It is guaranteed that there will be at least one valid solution for the given input.

Examples
groupSizes = [3,3,3,3,3,1,3][[5],[0,1,2],[3,4,6]]The first group is [5]. The size is 1, and groupSizes[5] = 1. The second group is [0,1,2]. The size is 3, and groupSizes[0] = groupSizes[1] = groupSizes[2] = 3. The third group is [3,4,6]. The size is 3, and groupSizes[3] = groupSizes[4] = groupSizes[6] = 3. Other possible solutions are [[2,1,6],[5],[0,4,3]] and [[5],[0,6,2],[4,3,1]].
groupSizes = [2,1,3,3,3,2][[1],[0,5],[2,3,4]]Constraints
