Ordered Matrix

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 20 3

3 10 2

5 11 15

Sample Output 1

1 2 3

5 10 11

15 20 30

Sample Input 2

2 5

-50 20 3 25 -20

88 17 38 72 -10

Sample Output 2

-50 -20 -10 3 17

20 25 38 72 88

LCM and GCD

You are given two integers

x and y. Find the GCD and LCM of the numbers.GCD: Greatest Common Divisor of two integers is the largest positive integer that divides each of the integers.LCM: Least Common Multiple of two integers is the smallest positive multiple of both the integers.Input

The input contains two integers

x and y separated by space.Output

The output contains

GCD and LCM for the given pair of integers.Explanation

Given

x = 6 and y = 14.The GCD of the numbers is

2. The LCM of the numbers is 42.The output is

2 42.
