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!

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