// Declare deque $deck = new DsDeque ( [ "engineer" , "for" , " engineer " ]); echo ( " Elements of first deque " );  
// Show deque elements print_r ( $deck );  
// Declare another deck $deck2 = new DsDeque ([ "practicing" , "data" , "structures" ]); echo ( " Elements of second deque " ); print_r ( $deck2 ); echo ( " Merged deque elements " );  
// Merge both decks print_r ( $deck -> merge ( $deck2 ));  
?>
Exit:
Elements of first deque DsDeque Object ([0] = > engineer [1] = > for [2] = > engineer) Elements of second deque DsDeque Object ([0] = > practicing [1] = > data [2] = > structures) Merged deque elements DsDeque Object ([0] = > engineer [1] = > for [2] = > engineer [3] = > practicing [4] = > data [5] = > structures)
