2491 - Divide Players Into Teams of Equal Skill.Medium
You are given a positive integer array
skill
of even lengthn
whereskill[i]
denotes the skill of theith
player. Divide the players inton / 2
teams of size2
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.Example 1:
Input: skill = [3,2,5,1,3,4]
Output: 22
Explanation: Divide 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.
Example 2:
Input: skill = [3,4]
Output: 12
Explanation: The two players form a team with a total skill of 7. The chemistry of the team is 3 * 4 = 12.
Example 3:
Input: skill = [1,1,2,3]
Output: -1
Explanation: There is no way to divide the players into teams such that the total skill of each team is equal.
Constraints:
2 <= skill.length <= 105
skill.length
is even.1 <= skill[i] <= 1000
