Method Summary

void	add(int i) Adds a new search at the end of the vector.
int	get(int index) Returns the indexth element of the vector.
boolean	isEmpty() Checks if the vector is empty.
void	removeLast() removes the search at the end of the vector.
void	restoreState()
void	saveState()
int	set(int index, int val) Assigns a new value val to the element index.
