resize
Syntax:
#include <vector> void resize( size_type num, const TYPE& val = TYPE() );
The function resize() changes the size of the vector to num. If val is
specified then any newly-created elements will be initialized to have a value
of val. The contents of the vector up to num will remain unchanged.
Example:
vector<int> v; for( int i = 0; i < 10; ++i ) v.push_back(i); v.resize( 20, 0 ); // adds an additional 10 zeros to the end of v
This function runs in linear time.
