Can you also start adding code files in the description maybe github repo or something else?

Good explanation but your mic is really low

Also pls explain the test case with a white board if possible showing the flow for easy understanding.

It will be helpful if you could explain the variables more clearly. And increase the volume a little bit. But otherwise great code. Thank you.

Does not look like we are using prevOperand at all. Why do we need it? Also can you explain why currentOperent == 0 needs to be checked at line21 ?

[samv]

Please explain curOperand . How is it different from val?
