Hi, In the problem's analysis they mention the use of backtracking to solve the problem: https://code.google.com/codejam/contest/2974486/dashboard#s=a&a=2
They also say that it's an easier approach, but maybe it's harder to validate if the configuration is valid than enumerate the corner cases? Does someone can show a solution for this problem implementing backtracking or point to some coder that implemented it?
