# --description--
|
|
|
|
Given a 2D array where each inner array contains (in this order) an idea name, an optimistic estimate, a realistic estimate, and a pessimistic estimate (in days), return an array of the idea names sorted by expected time to completion, shortest first.
|
|
|
|
Calculate the expected time to completion for each idea using the following formula:
|
|
|
|
- `expected = ((optimistic + 4 * realistic + pessimistic) / 6) * length of idea name`
|
|
|
