bbkane How can I recommend this to folks who want to learn SQL if the mathmatical operators aren't defined before questions are asked about them. It's pretty hard to google
set unionif you've never seen it before... I'd love some more explanation for the math.acme_104 The union of two sets A and B is a set of elements which are in A, B or in both A and B

LeoTM The union of two sets is the set of elements which are in either set (8).
The intersection of two sets is the set of elements which are in both sets (5).
sureshgvm0725 how the result is 8?

shahnawaz_jrw Answer is: 8
shitalb1 Hello there, you just need to enter how many elements are present in the union (AUB). You don't need to list out all. That's the catch :) Hope this helps!
pathivee27 I don't know how to write answer to the query. I know how to do mathematically but how to write here.
saurabhpansare11 They simply ask for number of elements in A U B
ijadou You i started to doupt everything around me, I know the result is 8, but when i submitted it showing "Wrong answer" ...
after a while, i was submitting the number with an extra space that made the answer wrong ..
so ((8) != (8 )) .. apparently ...
you know it is reallly ironic that your website teach programming, and you don't know about the trim() method ..
soni3164 No sample test-cases for this question. Please test your code against custom input.
raunakpandey1007 write only 8 and click on test against custom input---->run code
