Let a_n:{0,1,2,3,4,5,6,7,8,9,10} → S be an increasing sequence
where S = {0, 3.12, 12.68, 20.98, 30.53, 36.84, 43.21
, 65.41, 82.96, 91.22, 100}
Then for any n€[0,9], m€[1,850], both natural numbers,
a summoner passing seal n with rank m has the following score:
score = a_n + (a_(n+1) - a_n) * (m/850)
