How to solve first question?

Could someone share the abstract problem statements?

For the 1st question, you get the range [0,1] for p=1, [0,2,1,3] for p=2. The second array is double the size of first and the first half is just the double of the elements of the first array. For the second part you could just add 1 to the elements in the first part. This way you could use a DP approach.

I got 20, what about you guys?

Can you send me your code on whatsapp?

Me too, I also got 20

Last year’s cutoff was 25 so could it be that this year’s cutoff will be 20?
