iterator insert(iterator pos, const T &x)
Insert x before position pos.
void insert(iterator pos, size_type n, const T &x)
Insert n number of elements x before position pos.
void insert(iterator pos, InputIterator first, InputIterator last)
Range insertion.
Insert elements in range [first, last) into this vector before position pos.
void insert(iterator pos, const_iterator first, const_iterator last)
Range insertion.
Insert elements in range [first, last) into this vector before position pos.
The iterator pos in the functions must be a read-write iterator, can't be read only.
