B$.$ CASE PROBLEMScheduling a Golf LeagueChris Lane, the head professional at Royal Oak Country Club,

must develop a schedule of matches for the couples$$ golf league

that begins its season at $4$:$00$ P$.$M$.$ tomorrow. Eighteen couples

signed up for the league, and each couple must play every other

couple over the course of the $17-$week season. Chris thought it

would be fairly easy to develop a schedule, but after working on it

for a couple of hours, he has been unable to come up with a

schedule. Because Chris must have a schedule ready by tomorrow

afternoon, he has asked you to help him. A possible complication is

that one of the couples told Chris that they may have to cancel for

the season. They told Chris they would let him know by $1$:$00$ P$.$M$.$

tomorrow whether they will be able to play this season.Managerial ReportPrepare a report for Chris Lane. Your report should include, at
