A container that is similar to std::vector. Provides strong exception safety, uses RAII, and placement new operator. This container is efficient and its number of called constructors, assignments, and destructors are the same as of std::vector (see Benchmark test)
Singly-linked list. It uses the written custom Forward Iterator, provides strong exception safety, and has unit tests.
