Given a list of ordered pairs, find the order they should be placed in a line, such that the sum of the absolute values of the differences is zero.
list = [1 2 4 3 2 4
order = [1 3 2]
yields: [1 2][2 4][4 3] or: abs(2-2) + abs(4-4) or: 0 + 0 or: 0
There is a unique solution to this problem where the final score is zero.
Interesting...
awesome problem!
I finally figure out that you use '+length(list)' to index the second column of the list.
