Challenge #328: Booking a Flight? Think Twice!

I got a different answer for question #4. I don't think the sample output answer is correct with "44,777 cancelled flights". The starting input has about 94k lines of flight details, so if 50% of these flights were cancelled the airline industry would be in really big trouble :)

Please find my Solutions attached. Like others have said, the Output is kinda misleading and outright wrong for the fourth solution.

Questions not worded great and output made things a lot more confusing, but nice, easy challenge.

So #4 asked for the number of flights canceled in the summer of 2021. My answer was 25. I have no idea where 44,777 came from because out of 94,756 records, and there were only 1,530 cancellations. There were 73,254 flights in the summer, and I know the flights were bad but I'm pretty sure not half of the flights were canceled! That would be nuts!

Agree with everyone about Output #4 being an issue, but otherwise good!

Wording is definitely misleading, have to check others workflow to notice the count is the answer, not the sum of minutes.
