Problem: Let's define logical OR as an operation on two logical values (i. e. values that belong to the set {0, 1}) that is equal to 1 if either or both of the logical values is set to 1, otherwise it is 0. We can define logical OR of three or more logical values in the same manner:

<image> where <image> is equal to 1 if some ai = 1, otherwise it is equal to 0.

Nam has a matrix A consisting of m rows and n columns. The rows are numbered from 1 to m, columns are numbered from 1 to n. Element at row i (1 ≤ i ≤ m) and column j (1 ≤ j ≤ n) is denoted as Aij. All elements of A are either 0 or 1. From matrix A, Nam creates another matrix B of the same size using formula:

<image>.

(Bij is OR of all elements in row i and column j of matrix A)

Nam gives you matrix B and challenges you to guess matrix A. Although Nam is smart, he could probably make a mistake while calculating matrix B, since size of A can be large.

Input

The first line contains two integer m and n (1 ≤ m, n ≤ 100), number of rows and number of columns of matrices respectively.

The next m lines each contain n integers separated by spaces describing rows of matrix B (each element of B is either 0 or 1).

Output

In the first line, print "NO" if Nam has made a mistake when calculating B, otherwise print "YES". If the first line is "YES", then also print m rows consisting of n integers representing matrix A that can produce given matrix B. If there are several solutions print any one.

Solution (in PYTHON3):

Solution:
n, m = map(int, input().split())
tab = [[int(i) for i in input().split()] for j in range(n)]
ans = [[0 for i in range(m)] for j in range(n)]
for i in range(n):
    for j in range(m):
        z = 1
        for k in tab[i]:
            z = z and k
        for k in range(n):
            z = z and tab[k][j]
        ans[i][j] = z
tr = True
for i in range(n):
    for j in range(m):
        z = 0
        for k in ans[i]:
            z = z or k
        for k in range(n):
            z = z or ans[k][j]
        if z != tab[i][j] and tr:
            tr = False
            print('NO')
if tr:
    print('YES')
    for s in ans:
        for x in s:
            print(x, end = ' ')
        print()
