One thing i need to tell u don’t confuse with correct prime. u have to guess changed prime number. I thought correct prime was the first prime judge selected.There is ambiguity in question’s language.It wasted my time.

There is **no** ambiguity in question’s language.

Can you say that for CHFWAR? The cases P=1 and P=N are identical so we print 1 or N.

Can you say the same for CHFWAR? The cases P=1 and P=N are identical so we print 1 or N.

It is also mentioned in the question that you have to print minimum position so print 1

Just Reread problem again and again.
