## 문제

You have an $N$ by $N$ grid board, which is initially empty. You will write an integer to each cell, using each integer from $1$ to $N^2$ exactly once. Let $M_{i,j}$ be the integer written on the cell in the $i$-th row from the top and the $j$-th column from the left.

Let's define sequences $A$ and $B$ as follows:

• $A = M_{1,1}, M_{1,2}, \dots, M_{1,N}, M_{2,1}, M_{2,2}, \dots, M_{2,N}, \dots, M_{N,N}$
• $B = M_{1,1}, M_{2,1}, \dots, M_{N,1}, M_{1,2}, M_{2,2}, \dots, M_{N,2}, \dots, M_{N,N}$

For example, when the board looks like this,

1 3 4
2 7 6
9 8 5

$A$ and $B$ are defined as follows.

• $A = 1,3,4,2,7,6,9,8,5$
• $B = 1,2,9,3,7,8,4,6,5$

You are given integers $N, X, Y$. Find a way to fill in the cells so that the inversion numbers of $A$ and $B$ are $X$ and $Y$ respectively, or report that it is impossible to do so.

Note: an inversion number of a sequence $C = c_1, c_2, \dots, c_{N \times N}$ is the number of pairs $(i, j)$ s.t. both $i < j$ and $c_i > c_j$ are satisfied.

## 입력

Input is given from Standard Input in the following format:

$N$ $X$ $Y$

## 출력

If there is no solution, print 'No'.

Otherwise, print the answer in the following format:

Yes

$M_{1,1}$ $M_{1,2}$ $\dots$ $M_{1,N}$

$M_{2,1}$ $M_{2,2}$ $\dots$ $M_{2,N}$

$\vdots$

$M_{N,1}$ $M_{N,2}$ $\dots$ $M_{N,N}$

If there are multiple solutions, you can print any of them.

## 제한

• $2 \leq N \leq 300$
• $0 \leq X, Y \leq \frac{N^2(N^2 - 1)}{2}$
