The Pathfinder Challenges: Part 1

Warm up You are given a multi line string of integers representing a square grid. Every digit corresponds to a tile and signifies how long it takes to traverse this tile. If it's a zero, this tile cannot be traversed. You can move down and right. Your task is to write a function, which will return the time it takes to traverse the fastest path from the top left to the bottom right corner or -1, if there is no such path. The start and end point can be assumed to be traversible.
