Description

Input

Each test consists of multiple test cases. The first line contains a single integer $t$ ($1 \leq t \leq 130$) — the number of test cases. The description of the test cases follows.

Each test case is described by a single line, which contains two integers $n$ and $k$ ($2 \leq n \leq 1000$, $n$ is even, $0 \leq k \leq n^2$).

It is guaranteed that the sum of $n$ over all test cases does not exceed $2000$.

Output

For each test case, output $\texttt{Yes}$ if it's possible to construct a matrix that satisfies all of the problem's conditions, and $\texttt{No}$ otherwise.

If it is possible to construct a matrix, the $i$-th of the next $n$ lines should contain $n$ integers representing the elements in the $i$-th row of the matrix.

Note

In the first example, all conditions are satisfied:

• the sum of all the numbers in the matrix is exactly $0$;
• the bitwise $\texttt{XOR}$ of all the numbers in the row $i$ is $0$ for each $i$;
• the bitwise $\texttt{XOR}$ of all the numbers in the column $j$ is $0$ for each $j$.

In the third example, it can be shown that it's impossible to find a matrix satisfying all the problem's conditions.
