Middle matrix sums
Given an integer matrix,
m, with an odd # dimensions,
n x n, (e.g 3 x 3, 5 x 5, etc), find the sum of middle row as well as the middle column.
#Given [[1,2,3], [4,5,6], [7,8,9]] #Your program would output: 'Sum middle row =' 15 #(e.g. 4+5+6) 'Sum middle column =' 15 #(e.g. 2+5+8)
