Given a matrix that represent the distance along highways between major cities numbered 1 to N, provide the path and shortest distance from a given city, from, to a given city, to. Assume that 0 represents no direct path between two cities. If there is no solution to the problem, return -1 for both the path and the distance.

something strange with test cases 22, 23, and 25, the solution provided does not look like the shortest path (e.g. test case 22; the path 23-7-24-4-14 is shorter than the solution path 23-7-14), perhaps your solver is assuming triangular property of distances while the data provided does not have this property?
i'll look into it
I agree with you. i'm ammending my test cases now.
