Now we have a list of $$$2N - 1$$$ elements, and we know that even if these elements were independent of each other (same node does not appear in the list twice), the answer would be bounded by $$$\lceil\frac{2N - 1}{K}\rceil$$$. My solution's logic is sorting the array in increasing order and then choosing the lowest element. I may not give you give a concrete answer to your question because whenever there is a question of finding the shortest path or minimum distance in an unweighted graph the only algorithm that pops in my mind is bfs I have never applied dfs or rather never thought of it but I think you can apply dfs it 2. com/problemset/pro Contribute to SaruarChy/Codeforces-Solution development by creating an account on GitHub.
