Answer 1

Case 39:
Your code prints in this condition:
else if(seat[q]==3*i||seat[q]==i+14)
i is running from 1 to 108. At i=13 (13*3=39) this is true, but also at i=25 (25+14=39)
That's why it prints 2 times.
You should debug your code if it doesn't do what you expect. In the sololearn playground you can do this by printing out debug messages at different points where the error could happen. In an ide you can use breakpoints for this.

Answer 2

I tried to figure out what this code is even doing. Had to modify the formating for this. But what do these variables even mean? You need to explain what you are trying to do.
Here is the formated code:
