You are given a positive integer n. Construct such matrix 2n×2n that:
A submatrix is a contiguous rectangle of elements in the original matrix.
The first line contains an integer n (1≤n≤10).
On the very first line, print "YES" if the answer exists, or "NO" if not.
If the answer exists, print any such matrix on the next 2n lines, with each line containing 2n space-separated integers.
