The Vector class Vector
&reftitle.intro; A Vector is a sequence of values in a contiguous buffer that grows and shrinks automatically. It’s the most efficient sequential structure because a value’s index is a direct mapping to its index in the buffer, and the growth factor isn't bound to a specific multiple or exponent.
Strengths Supports array syntax (square brackets). Uses less overall memory than an &array; for the same number of values. Automatically frees allocated memory when its size drops low enough. Capacity does not have to be a power of 2. get, set, push, pop are all O(1).
Weaknesses shift, unshift, insert and remove are all O(n).
