I did add the bintree insert outsite the loop. The numNodes() increase but i cannot get the display because: words w(new_word) is inside the loop.
Btw, base on the code above the display go weird.
(newline here free)
... // word continue here until
num Node is: 23
there are 2 things on the display "More and 2This. two line stick together while others work fine ??? and newline automatically add there ???
