question: public final void push ( String s ) { if ( ( m_firstFree + 1 ) >= m_mapSize ) { m_mapSize += m_blocksize ; String newMap [ ] = new String [ m_mapSize ] ; System . arraycopy ( m_map , 0 , newMap , 0 , m_firstFree + 1 ) ; m_map = newMap ; } m_map [ m_firstFree ] = s ; m_firstFree ++ ; }
target:  Tell if the table contains the given string.
