Question: Give an algorithm that takes as input a directed graph with positive edge lengths, and returns the length of the shortest cycle in the graph

Give an algorithm that takes as input a directed graph with positive edge lengths, and returns the length of the shortest cycle in the graph (if the graph is acyclic, it should say so). Your algorithm should take time at most O(|V|^3). Write the pseudocode and explanation for it also. THX
