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:
m, n = map(int, input().split(' '))

matrix = []
for _ in range(m):
    matrix.append([int(x) for x in input().split(' ')])

a = [0 for i in range(m)] 
b = [0 for j in range(n)]

for i in range(m):
    p = 1
    for j in range(n):
        p = p & matrix[i][j]
    a[i] = p
#print(a)
for j in range(n):
    p = 1
    for i in range(m):
        p = p & matrix[i][j]
    b[j] = p
#print(b)
f1 = 0
f2 = 0

for i in range(m):
    for j in range(n):
        if matrix[i][j] == 1:
            if a[i] == 0 and b[j] == 0:
                f1 = 1
                break
            if f3 == 0: f3 = 1

        if a[i] == 1 and b[j] == 1:
            if f2 == 0: f2 = 1
            matrix[i][j] = '1 '
        else:
            matrix[i][j] = '0 '

    if f1 == 1:
        break

if (f1 == 0) and (f2^f3 == 0):
    print('YES')

        print(''.join(i))
