Write a Python script that read an n by n distance matrix in the format

<float> <float> <float> ...
<float> <float> <float> ...
<float> <float> <float> ...
.
.
.

from the file distance_matrix.txt and prints out the minimum number as well
as the i and j indices of that number in the matrix. The solution is 
essentially a continuation of the program we are writing in class.
