## Ordered Matrix in Increasing order

Given a M x N matrix, write a program to print the matrix after ordering all the elements of the matrix in increasing order.

Input

The first line of input will contain two space-separated integers, denoting the M and N.

The next M following lines will contain N space-separated integers, denoting the elements of each list.

Output

The output should be M lines containing the ordered matrix.

Note: There is a space at the end of each line.

Explanation

For example, if the given M is 3 and N is 3, read the inputs in the next three lines if the numbers given in the next three lines are the following.

1 20 3

30 10 2

5 11 15

By ordering all the elements of the matrix in increasing order, the ordered matrix should be

1 2 3

5 10 11

15 20 30

Sample Input 1

3 3

1 21 4

40 20 3

6 11 15

Sample Output 1

1 3 4

6 11 15

20 21 40

Code:

```
m,n=input().split()
m=int(m)
n=int(n)
num_list=[]
for i in range(m):
lines=input().split()
for j in lines:
j=int(j)
num_list+=[j]
num_list.sort()
a=0
b=n
for rows in range(m):
result=(num_list[a:b])
for i in result:
print(i,end=" ")
print()
a+=n
b+=n
```

Input

3 4

1 21 4 9

40 20 3 12

6 11 15 18

Output

1 3 4 6

9 11 12 15

18 20 21 40
