(Markov matrix)

An n by n matrix is called a positive Markov matrix ifeach element is positive and the sum of the elements in each columnis 1. Write the following function to check whether a matrix is aMarkov matrix:

def isMarkovMatrix(m):

Write a test program that prompts the user to enter a 3 by 3matrix of numbers and tests whether it is a Markov matrix.Note that the matrix is entered by rows and the numbers in each roware separated by a space in one line.

Sample Run 1

Enter a 3-by-3 matrix row by row:

0.15 0.875 0.375

0.55 0.005 0.225

0.30 0.12 0.4

It is a Markov matrix
