- Efficient Teams A coding competition is being organized on the HackerRank platform. The participants need to be grouped into teams where each team has exactly two candidates. There are
n
candidates, where each candidate has a skill denoted by skill[i]. A total of (
n/2)
teams are to be formed, such that the total skill of each team is the same. The efficiency of a team is defined as the product of the skill levels of its two members, i.e., for the-skills [1, 3], the efficiency of the team is
1∗3=3
. Find the sum of efficiencies of all teams that can be formed satisfying the criteria. If there is no way to create teams that satisfy the conditions, return
−1
. Note: It can be shown that the answer is always unique. Example The skills of the candidates are skill
=[1,2,3,2]
. They can be paired as [[1, 3], [2, 2]]. The sum of skills for each team is the same, l.e.,
4.
The efficiency is computed as: - Efficiency of
[1,3]=1∗3=3
- Efficiency of
[2,2]=2∗2=4
Return the sum of efficiencies,
3+4=7
. Function Description Complete the function getTotalEfficiency in the editor below. getTotalEfficiency has the followino naramatam. Function Desaription Complete the function getTotalEfificiengy in the editor below. getTotalEfficiency has the following parameter: int skill[n]: the skill of each candidate Returns long int: the sum of the efficiencies Constraints
