Dynamic String variable creation challenge

[shekhar_analyti]

Hi All ,

Let say I have a variable v_hold = Pic,Pen,Stand,PC,Lamp

And I have two buttons

I have a requirement in which

when a user presses  button Pen for first time then Pen from variable v_hold should be removed and

if user presses button Stand time then Stand should removed from variable v_hold  and result should be v_hold = Pic,PC,Lamp.

Now again if button pen is pressed then Pen should be added to v_hold and result should be v_hold = Pic,Pen,PC,Lamp

similarly if stand is pressed for second time then Stand should be added and v_hold = Pic,Pen,Stand,PC,Lamp
