You will be given a file with N = 200 different potential candidates. Every candidates has 6 different skills, with a score 1 <= s <= 10 for each.
The formulas to calculate their general value are:
	<skill>_score = round(6 * (int(s) * <skill>_weight)) + 10
	overall_value = round(5 * ((health * 0.18) + (agility * 0.20) + (charisma * 0.21) + (knowledge * 0.08) + (energy * 0.17) + (resourcefulness * 0.16)))
	Note: The round() function here is Python 3's round(), which uses a concept called Banker's Rounding
The weights for the 6 skills are: health_weight = 0.2, agility_weight = 0.3, charisma_weight = 0.1, knowledge_weight = 0.05, energy_weight = 0.05, resourcefulness_weight = 0.3  
Enter the first 14 candidates ordered in the highest overall values.
Enter them like so: Name_1 Surname_1 - score_1, Name_2 Surname_2 - score_2, ..., Name_i Surname_i - score_i
	e.g. Timothy Pempleton - 94, Jimmy Jones - 92, Randolf Ray - 92, ...
