@Sahastracookcoder1 when the code is successfully submitted you will see something like this , the picture that you posted only shows that sample testcase has successfully ran, so kindly click on submit, and make appropriate changes

[sahastrakishore123]

okay got that.

@dexterpuru I am not figuring any error in my code. And it's a runtime error with not proper error. So I am closing it. Will it be fine?
