'''
to_do:
    1->define function :decimal_to_hexa(),decimal_to_octa() & vise-versa
    2->check all errors and list them
    3->change the upper() method to something else
    4->examine time & space complexity
advanced:
    1->use Tkinter for GUI
    2->use CSS
done:
    1->check box,decimal_to_binary()
