Problem

You are given two matrices A & B of equal sizes and you have to check whether two matrices are equal or not.

NOTE: Both matrices are equal if A[i][j] = B[i][j] for all i and j in the given range.

Input

First argument is vector of vector of integers representing matrix A. Second argument is vector of vector of integers representing matrix B.

Output

Return 1 if both matrices are equal or return 0.
