Consider a matrix x
x = [ 1 2 0 0 5 0 3 0 8 ]
If we sum x along the rows we get
row_sums = [3 5 11]
Summing along the columns gives
col_sums = [4 7 8]
Metaphorically, we might call these sums "x-rays". Your job is to take these x-rays and reconstruct the matrix x being x-rayed, in the fashion of a CAT scan. Can you put all the bones in the right place?
All matrix elements must be non-negative integers. There is no guarantee of a unique answer. I will only check that the row and column sums match the supplied matrix, and that your elements are non-negative integers.
Bonus question: Under what circumstances does the answer become unique? Discuss.
