Set
Set is a collection of unique values. Apart from the common operations of adding and removing items from a set there are other operations that can be applied to a pair of sets.
- Union — This combines all the items from two different sets and returns this as a new set (with no duplicates).
- Intersection — Given two sets, this function returns another set that has all items that are part of both sets.
- Difference — This returns a list of items that are in one set but NOT in a different set.
- Subset — This returns a boolean value that shows if all the elements in one set are included in a different set.
