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 PYTHON):

Solution:
m, n = map(int, raw_input().split())
b = [0] * m
a = [[1] * n for i in range(m)]
mr, mc = [False] * m, [False] * n
for i in range(m):
  b[i] = map(int, raw_input().split())
  for j in range(n):
    if b[i][j] == 0:
      mr[i] = True
      mc[j] = True
b1 = [[0] * n for i in range(m)]
ar, ac = [False] * m, [False] * n
for i in range(m):
  for j in range(n):
    if mr[i] or mc[j]:
      a[i][j] = 0
    else:
      ar[i] = True
      ac[j] = True
for i in range(m):
  for j in range(n):
    b1[i][j] = 1 if ar[i] or ac[j] else 0
if b1 != b:
  print "NO"
else:
  print "YES"
  for i in range(m):
  	print " ".join([str(a[i][j]) for j in range(n)])
