# --description--
|
|
|
|
Given an array of 6 ice hockey teams and their records after the round robin games, determine the match-ups for the semi-final round.
|
|
|
|
- Each array item will have a team and their record in the format `"TEAM: W-OTW-OTL-L"`. Where:
|
|
- `"W"` is the number of wins in regulation, worth 3 points each
|
|
- `"OTW"` is the number of overtime wins, worth 2 points each
|
|
- `"OTL"` is the number of overtime losses, worth 1 point each
|
|
- `"L"` is the number of losses, worth 0 points each
|
|
|
|
For example, `"FIN: 2-2-1-0"` would have 11 points after adding up their record.
|
|
|
|
Find the total number of points for each team and return `"The semi-final games will be (1st) vs (4th) and (2nd) vs (3rd)."`. For example, `"The semi-final games will be FIN vs SWE and CAN vs USA."`
|
|
