       C++ Vectors
       Vectors contain contiguous
       elements stored as an array.
       Accessing members of a
       vector can be done in
       constant time, appending
       elements to a vector can be
       done in amortized constant
       time, whereas locating a
       specific value or inserting
       elements into the vector takes
       linear time.
       Constructors
       create vectors
       and initialize
       them with
       some data
       Operators compare,
       assign, and
       access elements
       of a vector
       assign assign
       elements to a
       vector
       at
       return a
       reference to an
       element at a
       specific location
       back
       returns a
       reference to last
       element of a
       vector
       begin
       returns an
       iterator to the
       beginning of
       the vector
       capacity
       returns the
       number of
       elements that
       the vector can
       hold
       clear
       removes all
       elements from
       the vector
       empty
       true if the
       vector has no
       elements
       end
       returns an
       iterator just
       past the last
       element of a
       vector
       erase removes
       elements from
       a vector
       front
       returns a
       reference to the
       first element of
       a vector
       insert inserts
       elements into
       the vector
       max_size
       returns the
       maximum
       number of
       elements that
       the vector can
       hold
       pop_back
       removes the
       last element of
       a vector
       push_back
       add an element
       to the end of
       the vector
       rbegin
       returns a
       reverse_iterator
       to the end of
       the vector
       rend
       returns a
       reverse_iterator
       just past the
       beginning of
       the vector
       reserve
       sets the
       minimum
       capacity of the
       vector
       resize change the size
       of the vector
       size
       returns the
       number of
       items in the
       vector
       swap
       swap the
       contents of this
       vector with
       another
       Notes:
       Note that a boolean vector
       (vector<bool>) is a
       specialization of the vector
       template that is designed to
       use less memory. A normal
       boolean variable usually
       uses 1-4 bytes of memory,
       but a boolean vector should
       use only one bit per boolean
       value.
