  1. Create an adjacency list from the roads array.
  2. Initialize a variable fuel to store the total fuel required.
  3. Define a recursive dfs function that takes a node and its parent as arguments.
    • Initialize representatives to 1 (for the representative at the current node).
    • For each child of node, if child is not the parent, recursively call dfs with child and node.
    • Add the number of representatives returned by the recursive call to representatives.
    • If node is not the root, add ceil(representatives / seats) to fuel.
  4. Call dfs with the root node (0) and a dummy parent (-1).
  5. Return the value of fuel.
