This is a simple brain teaser for you to play with.

A set is a list or collection of a well-defined but distinct objects.

Well-defined: Items in a set should share or have same properties. In other words, items or elements in the list should not contradict each other.

Distinct: Each object or item in the list is different from the other, not in properties but in the number of times it appears in the set, items may not be repeated.

Examples:

Set of Vowels in the English Alphabet = {a, e, i, o, u}
Set of even numbers greater(more) than 2 but less(smaller) than 10 = {4, 6, 8}
Set of shapes = (Circle, Rectangle, Triangle, Square}

Give an example of a Set in the comment box.
