Question

Please correct these code;--

def read_matrix():

   line = input()

   words =line.split()

   n = int(words[0])

   m = int(words[1])

   mat = []

   for i in range(n):

       row = []

       line = input()

       words = line.split()

       for j in range(m):

           row.append(int(words[j]))

       mat.append(row)

   return mat

def print_zig_zag(mat):

 

Zig-zag order in matrix;;

Input:---

4 4

1 2 3 4

5 6 7 8

9 10 11 12

13 14 15 16

Output :--
