WebSep 22, 2024 · Is it possible to have std::unique () compare two separate vectors? For example: - Vec #1 = {1, 2, 3, 4, 5} - Vec #2 = {0, 2, 10, 11, 12, 13, 14, 15} std::unique () would check both of the vectors and notice that they each have 2 as a duplicate so it would remove the 2 from both vectors but leave the rest untouched. Thanks! Aug 24, 2024 at …
WebUsing operator == for comparing vectors has two limitations i.e. It will compare all the elements in vector, we can not compare the sub sections of vectors using it. It will compare all the elements in vector, by calling operator == on each element.
