Understanding the Divide Players Into Teams of Equal Skill Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a positive integer array skill of even length n where skill[i] denotes the skill of the ith player. Divide the players into n / 2 teams of size 2 such that the total skill of each team is equal. The chemistry of a team is equal to the product of the skills of the players on that team. Return the sum of the chemistry of all the teams, or return -1 if there is no way to divide the players into teams such that the total skill of each team is equal.

Examples
skill = [3,2,5,1,3,4]22Divide the players into the following teams: (1, 5), (2, 4), (3, 3), where each team has a total skill of 6. The sum of the chemistry of all the teams is: 1 * 5 + 2 * 4 + 3 * 3 = 5 + 8 + 9 = 22.
skill = [3,4]12The two players form a team with a total skill of 7. The chemistry of the team is 3 * 4 = 12.
skill = [1,1,2,3]-1There is no way to divide the players into teams such that the total skill of each team is equal.
