CF1038B.Non-Coprime Partition
Non-Coprime Partition
Find out if it is possible to partition the first positive integers into two non-empty disjoint sets and such that:
$$\mathrm{gcd}(\mathrm{sum}(S_1), \mathrm{sum}(S_2)) \gt 1$$Here denotes the sum of all elements present in set and means thegreatest common divisor.
Every integer number from to should be present in exactly one of or .
Input
The only line of the input contains a single integer ()
Output
If such partition doesn't exist, print "No" (quotes for clarity).
Otherwise, print "Yes" (quotes for clarity), followed by two lines, describing and respectively.
Each set description starts with the set size, followed by the elements of the set in any order. Each set must be non-empty.
If there are multiple possible partitions — print any of them.
Note
In the first example, there is no way to partition a single number into two non-empty sets, hence the answer is "No".
In the second example, the sums of the sets are and respectively. The , hence that is one of the possible answers.
