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:

  for c in range(n):
    A[r][c] = 0

  for c in range(n):
    if A[r][c] == 1: return False
  return True

  for r in range(m):
    if A[r][c] == 1: return False
  return True



A = []
B = []
for _ in range(m):

  A.append([1 for _ in ints])
  B.append([int(x) for x in ints])

for r in range(m):
  for c in range(n):
    if B[r][c] != 0: continue
    zero_row(A, r, n)
    zero_col(A, c, m)

    if row_empty(A, r, n) and col_empty(A, c, m):
      print 'NO'
      sys.exit()

print 'YES'
for row in A:
  print string.join([str(x) for x in row], ' ')
