Given are an integer N and arrays S, T, U, and V, each of length N. Construct an N×N matrix a that satisfy the following conditions:

• a_{i,j} is an integer.
• $0 \leq a_{i,j} \lt 2^{64}$.
• If S_{i} = 0, the bitwise AND of the elements in the i-th row is U_{i}.
• If S_{i} = 1, the bitwise OR of the elements in the i-th row is U_{i}.
• If T_{i} = 0, the bitwise AND of the elements in the i-th column is V_{i}.
• If T_{i} = 1, the bitwise OR of the elements in the i-th column is V_{i}.

However, there may be cases where no matrix satisfies the conditions.

Constraints

• All values in input are integers.
• $1 \leq N \leq 500$
• $0 \leq S_{i} \leq 1$
• $0 \leq T_{i} \leq 1$
• $0 \leq U_{i} \lt 2^{64}$
• $0 \leq V_{i} \lt 2^{64}$

Input

Input is given from Standard Input in the following format:

N
S_{1} S_{2} ... S_{N}
T_{1} T_{2} ... T_{N}
U_{1} U_{2} ... U_{N}
V_{1} V_{2} ... V_{N}

Output

If there exists a matrix that satisfies the conditions, print one such matrix in the following format:

a_{1,1} ... a_{1,N}
:
a_{N,1} ... a_{N,N}

Note that any matrix satisfying the conditions is accepted.

If no matrix satisfies the conditions, print -1.
