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())

l=[]
ans= []
for i in range(n):
    k = list(map(int,input().split()))
    l.append(k)

temp = 0
count = 0

for i in range(n):
    for j in range(m):
        if l[i][j] == 1:
            flag = 0
            count+=1
            for k in range(n):
                if l[k][j] != 1:
                    flag = 1
                    break
            if flag != 0 and l[i] != [1]*m:
                temp = 1
                break
            if flag == 0 and l[i] == [1]*m:
                ans.append([i,j])


    if temp == 1:
        break

if len(ans) == 0 and count!=0:
    temp = 1


if temp == 0:
    print('YES')
    for i in range(n):
        for j in range(m):
            if [i,j] in ans:
                print(1,end = ' ')
            else:
