Hi Amisha, there are many errors in your code. Check the constraints, you’ll have to use long instead of int. Also, try solving this question by a ‘do-while’ loop.
And you also need to check the output format carefully.
Like at the end it should be “Invalid operation. Try again.” instead of “invalid operation.try again”.
