You receive a two-dimensional array in which each inner array contains customer-service ratings from 1 through 5 for a single representative. Compute each representative’s mean rating, then return those means ordered from largest to smallest. Treat the provided value as a 2D array, with one inner array per representative. Example input: [[4, 5], [3, 4, 4], [2, 3]]. Example output: [4.5, 3.67, 2.5]
Input: [[4, 5], [3, 4, 4], [2, 3]]
Output: [4.5, 3.67, 2.5]
