Sets

Also known as: unique distinct duplicates hashset membership contains deduplicate

● Beginner3 minBefore this: ListsSpec 2.2

A set holds each value once. Adding a value it already has changes nothing.

fn main() {
    const visits = ["asha", "ravi", "asha", "mira", "ravi"]
    let people = Set.of()
    for name in visits {
        people.add(name)
    }
    print(people.len())
    print(people.to_list())
}

The program ran and printed:

kavach run dedupe.kav

3["asha", "ravi", "mira"]
dedupe.kav: Kavach code, then what running it prints

Five visits, three people: the set kept each name once, in the order first seen. Use a set to remove duplicates, or to ask quickly whether you have seen something.
