One common way to find the shortest path in a weighted graph is using Dijkstra's Algorithm. Is it legal to enter a country you're a citizen of without using passport check points? Exercise: Extend the solution to print the least-cost path. I can correct only once each edge of the graph (this is the reason of the inequality $i, // Perform BFS on graph `g` starting from vertex `v`, // stores least-cost from source to destination. You are describing the Single Source shortest path problem. If the graph has a negative cycle, then there's no shortest (non-simple) path, and no best way to buy currency: there's always a better way that corresponds to walking around the cycle a few more times. The graph has 3 routes from source 0 to destination 3 with 4 edges. Notice that here the second maximal path somehow "correct" the first maximal path by taking $(v_1,v_3)\xrightarrow{-0}(v_3,v_2)$.
