Hey @pulkit10251
You are probably clicking on the RunCode button without giving the Custom Input.
Please provide the custom input and then only click on run. This exception here means that it is not receiving the input that it expects.
If the problem persists then save your code to online ide and share its link here so that I can help you out with the code.
