An e-sports tournament system stores player rankings in a 2D array named leaderboard. Each record in the array has the format [playerID, tag, score].

The system uses the following pseudocode program to sort the leaderboard in descending order of scores:

1  # leaderboard has the format [playerID, tag, score]
2
3  PROCEDURE sortLeaderboard()
4  BEGIN PROCEDURE
5      SET temp TO []
6      FOR outer FROM 0 TO LENGTH(leaderboard) - 1 DO
7          FOR inner FROM 0 TO LENGTH(leaderboard) - 2 DO
8              IF leaderboard[inner][2] < leaderboard[inner + 1][2] THEN
9                  SET temp TO leaderboard[inner]
10                 SET leaderboard[inner] TO leaderboard[inner + 1]
11                 SET leaderboard[inner + 1] TO temp
12             END IF
13         END FOR
14      END FOR
15  END PROCEDURE
