They have said at-least one of the P[i] will be equal to 1. in this case P[1] is 1. I suggest you to read the question again, its absolutely correct.

13

there’s no challenge problem?

Edited: sorry, I just read that 2 more problems will be added

14

When will it be added ?

15

But in constraints it is given
0<=Pi<=10^9
for every i

17

Why has this not been removed> ? I feel this question should be removed now.

18

This question is not being removed because Code Chef doesn’t own Stack Overflow and as you can see the post is already upvoted means it satisfied there rules and regulations of posting the question which doesn’t include Please don’t post the problem from ongoing contest. So, you get the idea why it not been removed. The best you can do is find out the code Chef user name associated with the user and tell Admin about it.

You shouldn’t have posted it here in the public forum if possible remove it and tell @vijju123 , @alex_2oo8 about it one to one communication.

I was granted score 100 for the Challenge problem after getting AC, and I can see I’ve scored 0pts for it now, and 100 is deducted from my total score, was my solution rejudged ??

As better solutions are submitted, your score keeps getting updated. This is to give people a chance to optimize.

Exactly, 0<=P[i] it means every P[i] will be greater than or equal to 0. Understand the basic maths. The question is absolutely correct.
