How to remove duplicate elements from a list?

Question

C++ / C#

Suppose we are given a list of objects of the class . How to remove identical elements from it? (For example, turn the list {a, b, a, c, b} into {a, b, c}) class Tlist<T>

Answer 1

In the general case, you sort, go through the list and remove adjacent identical elements.
But maybe it is necessary to solve the problem in a more radical way - instead of list, use a more suitable container - set? In set, the elements are already sorted and unique.
