Make Leaderboard

MediumP3Coding

names[i] scored marks[i] in a contest. Build the leaderboard:

  • Sort by marks, highest first. Students with equal marks are ordered by name in ascending dictionary order.
  • Students with equal marks share a rank. The next lower score gets the rank equal to its position in the list, so ranks skip (for example 1, 1, 3).

Return one string per student, formatted "<rank> <name>", in leaderboard order.

Example 1

Input
names = ["bob","amy","cal"], marks = [50,70,50]
Output
["1 amy","2 bob","2 cal"]
Why
amy has the top score. bob and cal tie, ordered by name, both rank 2.

Example 2

Input
names = ["a","b","c"], marks = [9,9,5]
Output
["1 a","1 b","3 c"]

Example 3

Input
names = ["z"], marks = [0]
Output
["1 z"]

Constraints

  • 1 <= names.length <= 10^4
  • names.length == marks.length
  • 0 <= marks[i] <= 10^9
  • names are lowercase letters, length 1 to 20
