A is a set composed of non negative integer arrays less than 5, and B is a set composed of non positive integers greater than - 4. Does the same number exist in set a and set B A is 0,1,2,3,4 B is - 3, - 2, - 1,0 The same number is 0 That's what I did, but the teacher said it was wrong If not, I will ask the teacher tomorrow
