Can somebody help me by providing a test case. I just ran a loop till N and check if it is divisible by any number. If then turn the check value to 0 and print no otherwise yes. But I am getting WA. Why???

U started loop from 2.
U should add a base case for p=1.
when p=1, answer should be “no”, ur answer giving “yes”.
Add this case before the loop.
Hope it helps! :slight_smile:
