Standard competition ranking (also known as "1224" ranking) assigns the same rank to matching values. Rank numbers are increased each time, so ranks are sometimes skipped. If we have 5 scores (the highest score having a rank of 1):

No matching values:

Scores = [99, 98, 97, 96, 95]
Rank   =   1,  2,  3,  4,  5

With matching values:

Scores = [99, 98, 98, 96, 95]
Rank   =   1,  2,  2,  4,  5

# Second and third scores are equal, so rank '3' is skipped.

Given a hash containing the names and scores of 5 competitors, and a competitor name, return the rank of that competitor after applying competition ranking.

Examples

competition_rank({
  "George" => 96,
  "Emily" => 95,
  "Susan" => 93,
  "Jane" => 89,
  "Brett" => 82
  }, "Jane") ➞ 4

competition_rank({
  "Kate" => 92,
  "Carol" => 92,
  "Jess" => 87,
  "Bruce" => 87,
  "Scott" => 84
  }, "Bruce") ➞ 3

Notes

The highest score has a rank value of 1.
