1. distinct() method

distinct() method is used to return a list that contains only distinct elements.

Method signature:

public fun <T> Iterable<T>.distinct(): List<T>

Work with simple list:

val simpleList = listOf(1, 2, 3, 5, 3, 4, 1, 10, 13, 7, 10, 8)
println(simpleList)
// print on console
//->
/*
    [1, 2, 3, 5, 3, 4, 1, 10, 13, 7, 10, 8]
*/

println(simpleList.distinct())
// print on console
// ->
/*
    [1, 2, 3, 5, 4, 10, 13, 7, 8]
*/
