# Column Sort

# --------------------------------------------------------------

'''

Given a matrix A, return a list of column indices in ascending order of highest column sums.

Assume no ties.

ex:

A = [

[1,2,3,4,5],

[7,4,3,2,-7],

[4,1,1,3,2],

[1,0,3,0,0],

[0,-1,9,3,1]]

Column sums:

Column 0 -> 13

Column 1 -> 6

Column 2 -> 19

Column 3 -> 12

Column 4 -> 1

So ordering these column indices by ascending highest sum, we return

[4,1,3,0,2].
