Task 02 (Graph Traversal Using BFS): You have most probably heard of Dora The Explorer. She likes to travel from one country to another. 43 1 3 3 2 1 4 Currently, Dora is at Doraland. Doraland is a beautiful country, consisting of N cities and M bidirectional roads. Recently, Dora has started to learn Graph Algorithms. She knows about BFS and DFS. However, since Dora is still learning, she is not feeling so confident and asks for your help. Dora contacts you and gives you all the necessary information about Doraland. Dora will start her journey from city 1. Now, your task will be to help Dora to find a path which is similar to the path of BFS graph traversal. Input The given map will be an undirected and unweighted graph. The first line contains two integers N and M (1 <= N, M <= 100) the number of cities and the total number of roads. The next M lines will contain two integers u₁, V₁ (1 <= U₁, V₁ <= N) denoting there is a bidirectional road between u, and v₁. Output Print the BFS path traversal which Dora will follow to explore the city, starting from city 1. Sample Input 1 Sample Output 1 1 342 (Another valid path: 1 4 3 2 ) Sample Graph 1
