WebMar 5, 2024 · I decided to give a try to LeetCode problem 133 Clone Graph. The idea is given the first node in a graph we need to generate a deep copy of it. A deep copy is a clone (not a shallow) copy of the graph. Given a reference of a node in a connected "undirected" graph. Return a deep copy (clone) of the graph. WebSay you use BFS, start at a node that’s -1 (hasn’t visited before) then set it to 0 (currently visiting). From there you go to the neighbors of that 0 nodes which are currently -1. And do the same thing. If any of those nodes are 0, that means there’s a cycle and you exit. Otherwise if you visited all nodes that can be reached using bfs ...
