Given a m x n 2D matrix, check if it is a Markov Matrix.
Markov Matrix : The matrix in which the sum of each row is equal to 1.
Input : 1 0 0 0.5 0 0.5 0 0 1 Output : yes Explanation : Sum of each row results to 1, therefore it is a Markov Matrix. Input : 1 0 0 0 0 2 1 0 0 Output : no
Approach : Initialize a 2D array, then take another single dimensional array to store the sum of each rows of the matrix, and check whether all the sum stored in this 1D array is equal to 1, if yes then it is Markov matrix else not.
