A graph traversal is a commonly used methodology for locating the vertex position in the graph. It is an advanced search algorithm that can analyze the graph with speed and precision along with marking the sequence of the visited vertices. This process enables you to quickly visit each node in...
The nextnn lines each containmm numbers (−1≤a[i][j]≤109) — descriptions of cells. It is guaranteed that the cells(1,1)and(n,m)are free. Output Output the minimum time it will take for Dima to get to school. If he cannot get to school at all, then output "-1". Example...
