Please check this challenge question
I am not getting correct hidden test. Please cross check it https://code.sololearn.com/cLI0DWt7WvHG/?ref=app
There asked to round up result so use ceil() function instead of round. And input is always >= , it's mentioned. So no zero outputs..
Jayakrishna🇮🇳 bt ceil will not round off as mentioned in the question
It's asked to round up* , not round off. So it mean apply ceil to the result. try it and see.
